Question about 1991 Toyota Pickup

1 Answer

1989 toyota 3.0v6

I recently had a new engine put in. Then the knock sensor had to be replaced. After this the engine started running hot, I was losing coolant, and I noticed oil leaking out from around one of the head bolts. Thinking there was some kind of leak in the system, I added a stop leak product the the radiator. Turns out the mechanic forgot to replace a clamp on one of the hoses. Now I am not losing coolant, but the engine stills runs hot sometimes. Do you think I might have clogged the radiator? Also, will removing, sealing and retorching the head bolt stop the oil leak? The engine runs great and the exhaust is invisible. No funny smells.

Knocking sound from engine..

How many miles on engine? Was oil changed after it ran hot? Install a good mechanical oil pressure gauge to see what is really going on. Also might use length of hose put one end in ear and listen with other end to locate exactly where noise is coming from. BE CAREFUL NOT TO STICK HOSE INTO SPINNING PARTS. If noise is from bottom of engine bearings may be shot. However, it could be mechanic left some part loose and that would be an easy fix.

We made the terrible mistake in buying a Toyota Previa long distance. We love them and this is our third, but this one, a 1996 Alltrac, arrived with a seemingly unsolvable problem. This car has no power....

Accessing the knock sensor is not a hard job when the front seats and floor are removed, should take no longer that 2 hours at a dealership. It is a common fault for the knock sensor to fail & will give obvious problems with power. Also, the check engine light should illuminate. Very sorry you have had to spend this kind of money.

Normally on chevy ignition modules when they go bad, they will quit when they get hot & after cooling down will work again, so when you have them tested they have cooled down. I would try changing it & see if it wont fix it.

90 Toyota 4Runner pinging noise

hi the pinging you here is ignition firing before it should but if you have a knocking noise i would suspect the worse but try doing a compression test first see if everything is in order then if this seems ok have you put fuel in it just before it started if so change your fuel if not see if the electrical system has a knock sensor if so run the engine and tap the block close to it see if engine revs drop if not replace but the knock is a piston best of luck yates210456
