[Power Steering Fluid]

They are NOT the same, and being around MANY Celicas with the same driveline, what you will probably experience first is leaks starting, including the infamous "alternator lubricator", and then lines starting to bleed through.

I would reccomend draining the steering fluid and putting in the correct Dexron ATF - BTW, there is no "T" in Dexron.

[To Swap or Not to Swap]

Apparently it needs a valve job. This is the original 2.2 4cyl with 4 speed standard, 30,000 miles. Since at some point we may take it West (we live in WI but are from Idaho where there are real mountains), we are considering changing engines. Options are: do the valve job; put in another, newer 4cyl; or going to a 6cyl.

That is a 2.4L 4 cyl. The 22 is model #, not displacement. The 20R is a 2.2L, but was upgraded to the 2.4 in '81.

I agree with the valve adjustment - usually goes a long way, but my recommendation - and I work on a lot of these, specializing in RWD Celicas- is adjust them HOT, and one cyl at a time - #1 TDC, timing mark aligned, adjust intake and exhaust, turn engine 180 degrees, adj #3, then another 180 degrees and the timing mark will line up again for #4... Oh, and adjust to a "modified" .007 intake and .010 exhaust.

If you are looking to replace the engine, use an '85 and later engine, as they have a slight bit more power due to a complete redesign by Toyota, and ensure that it is rebuilt with a steel timing chain guide!

[Carburator Swap?]

The Weber passes emissions here in Oregon, but all they look for is a cat with a mirror under the vehicle, and that it passes an exhaust sniffer - they don't open the hood. My Corona passed two years ago with a Crane (TRD) stage 2 cam and ported and polished 20R head. I'm going through this week, so we'll see if it passes with a Comp 280S cam!

The Weber is very simple, and if you can play with the jetting, can net a very clean exhaust and great fuel mileage, besides getting rid of the spaghetti factory of vacuum lines under the hood. There is also an "emissions" version. eBay has about the best prices for the complete carb kit - about $275 with adapter plates, air filter...

I went for the stock look with the air filter though - which keeps the heater on the cold air snorkel.
