weird noises pls help *look*

My guess is one of the pulley bearings has failed - remove the belt and turn each pulley by hand to find which one is stiff/rough.

 

cant hear anything screeching. but if it sounds like a really high pitched squeal it could be air squeezing out of a faulty gasket

 

If it is a pulley bearing and it fails it will eventually throw the belt and you will have no power steering and no water pump......however it may last for a few days (if that's the problem). It only takes a few minutes to check if it is a pulley and it is very cheap insurance compared to a seized engine which is the worst case scenario.

 

Locate the tensioner pulley - thats the one that applies tension to the belt - put a ring or socket spanner on the bolt head of the tensioner pulley and rotate ANTICLOCKWISE to take tension off the belt...remove belt but first note how it fits on the pulleys....draw a diagram. The tensioner pulley bolt has a left hand thread so you must turn it anticlockwise to rotate the tensioner.....do it slowly and gently.

 

what the **** .... on my computer it sounds like a knock or piston ... get a long screwdriver and with the handle to your ear touch the other end against various places on the motor and it shall act like a automotive stethoscope and find the source of the noise

 

Could be just the speakers on my computer but that sound combined with your description kinda sounds like your mate has spun a main bearing, though hopefully im way off otherwise I would have said its one of the bearings in a pulley.

 

well at least your mate is honest with you. This is what i would do

1) pull out the spark plugs on the noisy side one by one. Look at them, look for damage and wear. If there is damage we know that there is either metal floating around your engine and that, that is the damaged chamber. If it is worn them replace the spark plug, you might just have a terrible miss

2) Take the rocker cover off, take care not to snap the screws holding them in. While you can see the rockers rotate the engine by hand and see what valves are in which position when the sounds is made, then refer this to what we know from looking at the spark plugs to determine if its inlet or outlet valve.
If its one of the valves, you can either take your car to a mechanic, or rip the head off and take it there. Id suggest not driving it as you will be doing damage to the bottom end.

3) If its not the valves and all are working, but the spark plugs are stuffed then change them and see what happens.

4) Check the coolant for oil and oil for coolant. There will be a creamy residue in the oil if it has water in it.

REPORT BACK.. Ill have a think and let me know

 

For your sake I'm hoping it turns out simple. Re the pulleys, you say one is stiffer than the others and you'd post a pix - when they get rough the sound can travel via the serpentine belt and appear to come from somewhere else and be pretty noisy.

 

it should of taken a 6k my old ecotec with 300,000ks sat on the limter for a while and was fine. now that engine has been in 4 different cars lol and still going strong.

where does the sound come from can you tell? which pulley was harder to turn than the rest???

 

*** is your mate gonna pay for ya new engine lol? see if you can find a l67 and drop that it

 

thats crap let your mate borrow the car and he treats ypur property like that some mate hope he helps with fixing it i know somebody if he was my mate i wouldnt be letting him borrow my car ever again borrow his car and thrash it see what he says when you give it back to him with a blown engine
