LOUD SQUEAK FROM ENGINE?????

[bullittcraig]

Iv`e run out of ideas of what it could be. Its a 1600 standard crossflow engine. Only happens on idle when engine is hot. It sounds like a belt slipping only louder. It is definately in or around the engine and im begining to think its inside as iv`e looked at everything else. I have also noticed that the oil pressure drops very low on idle but anything over 1000rpm`s and the pressure is great. I thought it may have been the rocker shaft dry of oil but its definately not that. Any ideas?

your oil pressure dropping off a bit at low revs is normal matey, wouldnt worry about it. as for the squeak it could be a number of things. does the noise go when you depress the clutch ? can you move the crank forwards and backwards in the block ? try checking these things, its where i'd start looking

 

 

ps if the thrust washers are knackered the flywheel can rub on the back of the block and the crank can rub on the block inside (had the same problem myself)

squirt wd 40 in to the alternator and see if it go'es

an update on what i checked today. Tried running the engine without the fan belt, made no difference. Checked for excess movement on the crank and couldn`t move it. Any other ideas?

you checked for any wildlife/pets under the sump, could have a half dead cat down there, hehehe.

my alternator used to squeek like a bitch when run under 1000rpm, is there anyway you can disconnect the alternator while running the car?

i cant for the life in me think if theres a separate belt for the alternator :\.

 

is it high pitched. low pitched. changes with engien revs etC??

LOL. Checked for all wildlife and no joy. Removed the fan belt which then cancels out alternator and water pump, still the same. It only does it when engine hot and below 1000rpm. It is fairly high pitched but bloody loud. Does sound as if metal to metal. Once you rev the engine then it stops.
