82 22R engine white smoke
« on: Jan 10, 2021, 09:56:55 AM »
I bought an 82 pickup 4wd last spring from California and had it shipped to me in Kentucky.  It was in good shape and kept in storage. Supposedly the po was going to restore for his daughter but she wanted something else. He bought it from an old man that mostly pulled it behind an RV for camping trips. When I got it there was around 113,000 miles on it.  It now has about 117,000 miles

It runs reliably and well. Its my daily driver.  But it does have some issues.   When I first start it up it has white smoke but after running for a while the smoke goes away.  Ive also noticed it burns about a quart of oil every 1000 miles.  The oil looks good and I dont see any water in the oil, but over the past couple months Ive noticed the radiator level has dropped about an inch. I see no leaking oil on the concrete, but where the mechanical fuel pump is located it looks oily. I think my fuel pump needs replacing but it might be leaking oil in that area where the head meets the block.  I need to further investigate. 

I want to do a compression check and want a good made in the USA kit. Anyone have a recommendation?  I see that GSI Industries makes a made in the USA kit. Anyone have experience with them?

Ive also noticed my truck has been idling very high lately.  I suspect a vacuum leak is causing it. I hate that floor mount gas pedal too. It seems to attract dirt and grime causing that to get sticky at the hinge.  My dipstick is so loose that it could cause a vacuum leak. I see Jim at 22RE performance has a new tube and dipstick for the 85-95, but I dont think that will fit my 82.

So I plan to check my compression and do a leak down test.  Figure out where my engine stands and source my problem.  Im hoping its not a blown head gasket.

Im hoping I dont need a rebuild just yet, but if I do should I rebuild this block or get an 85 or newer block?  I know that a lot of things are different with the old blocks like mine and you cant get new heads for the older ones. 

Any recommendations?

How does it start? Does it fire after a couple of cranks at most, or does it have to crank for 5-20 seconds?

Hey G.

You should have some good input from some very experienced guys on this forum.

Getting info from Jim at 22RE Performance is a good idea.

The compression check and leakdown tests should tell you whats going on with your engine.

From your description I have a bad feeling its got head gasket issues, and a quart of oil in 1,000 miles is excessive and you will probably get some low compression numbers.

Before you decide to rebuild the engine, I highly recommend you do lots and lots of research and get lots of opinions from some experts and those suppliers of parts. In my limited experience, there seems to be DIYers out there that can do a rebuild very successfully and those who have problems.

If you choose to buy a long block as an option to rebuilding the block from scratch, I highly suggest you do lots of research into whos long block will work best for your budget and desired quality level.

I believe that to rebuild one of these early Toyota engines takes a lot more skills, knowledge, time, and money if you want it to go 200K or 300K miles, than some guys have claimed.

I suspect I will soon need a rebuild. This engine feels tired so am guessing Ill have some low compression numbers.  Id like to wait on the engine if I can because I was wanting to pull my bed and have it dustless blasted and work on it before tackling the engine.

Do you have a recommendation on a good compression tester? Preferably American made?   If I do have bad numbers and have to rebuild I would either get Jim to build me one or I could try to rebuild mine.  If I get a newer block Id have Jim build it.  Jim wont rebuild the old blocks.

I guess Im wondering really if I should rebuild this block or just get the newer (85+) block

Another question: Do you use synthetic oil? I seem to remember hearing tales of synthetic oil leaving white smoke when it burned.

A leak down test will tell you more than a compression test and more than I ever can from the other end of an internet connection.

When I changed the oil I put in amsoil synthetic.  I think the po had Castrol synthetic in before

I have never had a 2 gauge leak down kit. I have found a made in the USA leak down kit and a compression kit from GSI.  Would I need both?

Here's my latest purchase:...

There are lots of choices and prices range.

White smoke at start up is typically steam/coolant from cracked head or blown head gasket.  White smoke after normal op can be synthetic oil burning.  Oil burning should be seen during hard acceleration.  Have you pulled the spark plugs?

Your truck is exhibiting many symptoms of coolant leaking into one or more cylinders, whether by a blown head gasket or a cracked head or block. A distant second would be burning synthetic oil.

Oil burning at start up can happen if you park your truck facing uphill and a pool of oil stays under the valve cover and drips past the valve guides and seals into cylinder #4; mine has done this on a few occasions.

My experience with blown headgaskets is rather limited, but the one vehicle I had with a bad head gasket had to crank for about 20 seconds before it could clear the moisture out of the cylinders and fire.

If you have unlimited budget, I would get both the compression tester and leak down tester. If I had only one, my personal preference would be the leak down tester.

Release the pressure of the radiator as soon as you can after shutdown (wait until it won't boil over with release of pressure).

This will prevent the cooling system pressure from forcing coolant into the engine as it cools overnight.


See what happens next day.

This looks like a nice compression tester for the money.

It looks like it's American made, but I find it difficult to verify where things are actually made.
