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 what’s going on with your engine.From your description I have a bad feeling it’s 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 who’s 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.Gnarls.
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.
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:...https://www.amazon.com/INNOVA-3612-Compression-Tester-Piece/dp/B000EVU89I/ref=pd_di_sccai_1/142-5226433-2262460?_encoding=UTF8&pd_rd_i=B000EVU89I&pd_rd_r=dd9b712e-b547-4df7-82d9-0e55b0d1d819&pd_rd_w=QKOx5&pd_rd_wg=3Y6WX&pf_rd_p=c9443270-b914-4430-a90b-72e3e7e784e0&pf_rd_r=3T3MH40QVFW5JKGXP9V4&psc=1&refRID=3T3MH40QVFW5JKGXP9V4https://www.amazon.com/OTC-5609-Cylinder-Leakage-Tester/dp/B0030EVL60/ref=sr_1_12?dchild=1&keywords=leakdown+test+kit&qid=1610309998&sr=8-12There 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?Gnarls.
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.
A leak down tester requires compressed air.
