new RVowner

Bought 6 Hankook 185r14 8ply 65psi 1800+ load rating tires and have them on my mini for a few years now. We had a tire get a flat (darn screws in the road) and need to replace one. Is there any difference to these tires and can I put one of these RA18's on the dually (rear) without any problems? Here are the pics for each tire, And they seem to have the same specs.....

it was happening before we took it to them, As you drive it, it feels like presure is building up in the brake pedal and it gets tighter as the engine heats up. every once in a while it kinda lets go and then tightens up again. i was just seeing if you guys would give me a second opion before i go back to the same people to try to fix it again. fixing these things is not cheap. lol i was hoping it was just the calipers and not the master cylinder or the booster. here's the next question, if i do the master, should i do the brake booster as well? and how much should it cost to have those 2 things changed, apx? 1984 toyota rader 22r

When we drive the rv, the front brakes get very hot and you can feel the heat even on the hubcaps. We just had them bled, new calipers, new brake lines from the calipers to the hard brake lines. when we drive, it feels like i am pulling another rv behind us. So we come to you awesome guys & gals to figure out what could be causing this and how we can fix it right away. Thank You is the brakes fluid not releasing, or the master cylinder is bad or brake booster maybe, or brake push rod not right, or sticky brake pads or ? edit: 1984 toyota rader 4-speed manual motorhome

We already have the small breather coming from ebay to go on the front hole. All we need to do is figure this out with the back hole. What do these holes do anyway? I assume they bring fresh air in the crankshaft area to push out heat and un burned gases? And then those gases get re-burned in the engine? Does this help keep the motor running a little cooler? Does it help with the mileage at all? And we have been driving our toy for over 2 years with it this way because we had a shop install the weber carb long ago and that is the way they left it. did we hurt something maybe by it being this way? sorry for all the questions, we are learning as we go. lol ok, here is what we have for the booster.

nice, thank you guys again for all the help Can't wait to see those pics. That front hole has been plugged for 2 years, That should have had fresh air going to it all along, yes? (i assume to help cool the engine crankcase maybe, or to help get out that pressure buildup out) Did that maybe cause any damage to anything by not getting the fresh air it needed for all this time. (never going to that guy to fix my truck ever again, seemed like he was not a good as he thinks) And thanks to you guys here on this forum, we are learning to fix things ourselves.

Thank you guys very much for all the help. Ok i will order the breather in the second link you had to put that on the front hole. (as for the back hole (i have nothing left from the kit that i had installed 2 years ago, that is all gone.) So that hole has been open like that for 2 years now so, what do i have to buy to get that hole to go to the right place? hose, clamps, etc the trouble that we are having is ours still has all the emissions stuff still on it and if we ran a hose from the back hole to the ????> LOL (the part that the hose would connect to does not look anything like what we see in that picture) sorry, we are new at this It should go into this area, yes? Thank you again for all the help, there is just so much extra stuff from the emissions and the old carb left, we are learning as we go.

we are having a bugger of a time understanding where they go...... here is what ours looks like.

i agree, had ours for over 2 years now without a single problem. we were just wondering why there is a open hole on the top of the engine like that and why the other one is plugged. i found these pics online just now and they show another way to use these top holes.....we are pretty lost trying to figure these out. LOL

here is the carb contents (i am pretty sure this is what we bought)

Ok, So it should go under that big breather rather than be plugged, yes? we don't have that small white pvc piece, is that something extra you have to buy?

Here is what my carb looks like. In the last picture, you can see that there is a hole under the air filter on the right side. Is this the hole that you are talking about?

any possibility of a picture so i don't screw something up? lol You are talking about the second picture up there ^ correct?

ours is the first picture, what should i do to fix what you see in the picture? leave the first one alone with the cap, or install a air filter thing like in the second picture? Back one to the base of the carb?

The 2 ports on the top of an 22r engine (front & back) Where are these ports supposed to be hooked up to? (This is how they installed the weber carb 2 years ago, but every picture i see of that engine with the swap has them connected) As you can see, They plugged the front one and just left the back one open. note: the first picture is mine, And the second is a picture i found on the internet. Thanks for your helps guys

UPDATE: we just checked all of the exhaust that we had put on.... 2 inch cat -----> 2 inch straight pipe -----> "1 3/4 muffler" Did they put the wrong muffler on it and that it why it is acting so weird? too much air that can't get out fast enough because of the small muffler? Bottle necking at the muffler? Too much back pressure causing the engine to heat up and lose power maybe?

i forgot to add more info about the mini. 1984 toyota rader, 22r, 4 speed, brand new weber carb not the 38, but the other one. (34 /36 ?) it ran great and i really did average about 16 miles per gallon. (no jokes) (had the new weber carb on there for about 1-2 years now) The lowest i got ever was about 15, and then all this just happened with the increase of the engine heat, lower mpg, lack of power on the freeway etc And this little guy used to just cruise down the freeway at 60-65 no problem at all. now we have problems getting up hills and then we had the cat removed and replaced and they took out that little sensor thing from the cat and never put it back with the new one. where can i buy just that and maybe put it back on somehow?

Ok, well we don't have one right now because the guy took it off when we replaced the cat with a new one. Is this something that needs to be put back on? We noticed that when he took that off, the engine was running just a little bit hotter, and it seems to be lacking a little power on the freeway. Plus, we used to get 15-16 mpg, and now we are down to 12ish. Or is something else wrong? There seems to be a place for one on the new cat, there is a small hole that looks like it should go there.

Yes, That is was it was. we threw it away. never used it anyway. (re-ran the vacuum hoses) Thank you here is another question for you guys and gals out there. This is a picture of what we had on our 1984 22r toyota rader. (Pic found from the internet, but ours looked the same) What is that sensor/probe on the cat? Oxygen? Heat? We put a new cat on and the new cat does not have that on it so the mechanic just took it off. (Good or bad to not put one back on somehow?)

1984 toyota 22r engine the plastic broke away from the mount and it was laying on the engine, long story short.....it melted.

Thank you. That was some info i was looking for. We cruise this little mini at 60-65 and it runs fine. with that info, do you think that would help the engine at those speeds?

What kind of mpg are you getting with that setup? Mine has always gotten around 15mpg (The best i ever had was 16.5mpg) And that was with a cat with holes in it and a muffler that was falling off. What a 22r get better mpg and horse power just running straight pipe. (i know, it would be very loud) but i was just wondering. Setup: 1984 toyota 22r manual 4 speed

Thank you for the opinions guys The cat and everything back is all junk and has to be removed anyway. So i was wondering if i went to 2 1/4 instead i might gain 1 or 2 HP for the freeway. As all of you know, These toyota rader motorhomes have 22r engine in the older ones and i love these little buggers, You can beat that engine with a stick and it just keeps going, But they don't have much power at all for the task that they have to do with a house on their shoulders, and i figured 1 or 2 HP might help a little on the freeway. lol note: Going from 1 7/8" to 2" is almost nothing compared to changing it from 1 3/4" to 2 1/4" (That would be 1/8" to 1/2") <---- that's eight times the size increase that you had so maybe it would help on the freeway to get that air out of that little engine ?!?!?!? I was thinking of just running straight pipe to the muffler and call it a day (2 1/4" or 2 /1/2") + NO CAT What do you guys think?

would it help at alll with the horse power & mpg if we put 2.25 inch exhaust pipe in our 1984 toyota rader rv? Or would it help or hurt with the performance at all? we have 1 3/4" stock pipe & muffler on there now thank you.

Thanks guys for all the infomation. I just checked again, and the tires that are on this thing now are firestone 440 or something 195 85 r 14 M&S (Front) firestone 440 or something 185 85 r 14 M&S (Back) I think they put the wrong tires on this when i bought it from the guy. I think the tires that he put are there are car tires. (Good thing i have not driven it since i bought it 1 year ago) (Safety first you know)

I have found these so far........ What do you guys think? My link My link 2 But i am still looking to see if there are any more options. Plus, Are the tires the same all the way around? Front to back? We have 6 tires on this model and i just want to be 100% sure. (this might be a silly question, But this is my first motorhome) 185r14 (load d) x 6
