New guy with a question....

this is my first post.i just got a 97 ranger with 4 cylinder for my son.was driving home form the body shop and it started making alot of noise in the valvetrain, it sounded like they were loose..but it would come and go until it finally just made noise all the time. checked timing it was off 10degrees past TDC, checked compression it was good..did a leak down all cylinders 8 %(193k miles)tore it down it was still in time..but replaced belt and tensioner and cam timing sensor and now it is 10 degres TDC...and still makes the noise..any suggestions...because i am at a loss.

Re: New guy with a question....

If you're sure it's coming from the valve train, I'd pull the valve cover and see what it looks like in there. Are any lifters or rocker arms loose. Is it pretty clean, like the oil has been changed regularly. The Catalytic convertors can come aprt inside and rattle that sounds like the valve train. Listen underneath too.

Welcome to the forums.

Re: New guy with a question....

yea did that..everything was tight..it has 50 lb oil pressure at idle..it ran good but the noise is crazy never heard anything like it..i am wanting to think the lifters may be collapsed. i dont know what oil was in it but after i heard the noise i put a new oil filter on thinking it may be clogged and loosing oil pressure...i dont know what kind of oil or how old is in it so i am going to change it tomorrow and see what happens. i was tinkingit was a timing issure but so far it is not that...thanks for the advice

Re: New guy with a question....

When the valve cover is off, you can try to see if there's any excess looseness in any of the lifters by turning the engine over every so often and check them one at a time. Does it sound like only 1 or more than 1?

Re: New guy with a question....

Thanks for the update. Hope you got it cheap enough to cover that cost.
