Question about 1990 Toyota Pickup

1 Answer

2 valves losing compression

Almost two years ago I made the fatal mistake of having Walmart change the oil in my pickups. The 1990 SR5 lasted 3 days after the oil change. A vicious person drilled two holes in the filter that walmart put on my truck. I had the motor rebuilt, and the truck ran wonderfully. Now two of the valves are losing compression. I still have 3k out on the loan to have the motor rebuilt. There is no recourse with the mo*on I had rebuild it. I have been quoted $2500 + to do the valves on this truck with no guarantee that the bottom end is any good. The truck does not smoke. My son who owns the truck is mildly autistic and is very attached to this truck. Any words of wisdom? Is it worth it to sink more money in it? Toyota wants $6500 for a new rebuilt motor and I can pay $100 a year for an extended warranty. Oh, BTW the truck has less than 135k original miles on it. Not much for a Toyota.. any help would be appreciated. My son is devastated. Thanks! Spark.. Denver, Colorado

Don't bother rebuilding. If it lost oil . it's a goner. Check around town and see if anyone sells used Toyota motors shipped from Japan. They have to get rid of all vehicles with 50.000 miles by law. Wholesalers in the USA buy them cheap! I got one for my 87 MR2 for $1200 installed. Runs like a champ! SR5 engine are very popular , so you should have no problem finding one in a large town like Denver. Remember, get a warranty, even if it's for 90 days. Gives you that warm and fuzzy feeling! :)

1990 Honda Accord DX 5 speed no power/2 cylinders not firing? far as the oil on them it is possible it is only the spark plug tube seals located on the inside of the valve cover,in fact if you can remember when you took the old plug wires off the boots of a couple propably had oil on as far as the real problem I would recommend checking the timing belt it is possible it jumped time,its pretty simple just remove the valve cover(gonna replace the seals anyways)and top timing cover.roll the engine around and look for the cam and crank marks.if you need anymore suggestions or help let me know have a good day DB

2001 Grand cherokee 4.7 low oil pressure in cold weather.

I'd suggest using a good brand of synthetic oil (which was actually developed a really long time ago for the armed forces for use in polar reigions) Most flushes loosen too much material all at once, causing blockage of the oil pickup screen. You can get a bit more cleaning and lubrication protection by adding a bit of marvel oil to the synthetic. Change just the filter (and lost oil) about every 1500 miles, till the problem subsides.

Smoke at start up

The Stop Leak products might work short term but some of the additives can cook off and become varnish in a hot engine and also whatever swells the seals will harden them over time.
This is the procedure to replace the valve seals with the engine in the truck and there is minimal tear down required
remove the valve covers and spark plugs.
get a compression tester , remove the valve core.
install the compression tester into the spark plug hole. connect the air hose to it.
use a valve spring tool to compress the valve spring.
Use a pocket magnet to remove the keepers.
remove the spring and install the valve seal.
This would be a nice time to upgrade the valve springs.
Make sure you do only one cylinder at a time with air connected to the cylinder you are working on.
This keeps the valves from falling down into the cylinder

However i also have a 1990 chevy pickup with a 5.7 liter in it and it has given a puff when you start it for several years and it uses little oil between changes so unless it consumes vast amounts of oil or has problems with passing an emissions test (If applicable) your money will be much better spent elsewhere.
hope this helps.....Good Luck!
