2v newb with timing issue

94gtfreak · Oct 8, 2019

Been a while since I've been on here. Recently purchased a 2002 GT 5 SPD for dirt cheap because it had a "tick". Thru minor investigation I had narrowed it down to a chain/tensioner/guide issue. Replaced said parts, put it all back together and BAM......same issue! Noise only presents itself under acceleration around 1500 to 2300 rpm and pretty much any time under load (for the same rpm range) Noise comes from front passenger chain/tensioner area again. Is it possible I got another set of crappy tensioners or have an issue before said tensioner? Any help is appreciated!

Their may not be sufficient oil supply to the tentioner. Negligent oil changes, high miles, cause sludging in oil gallery's that have a low flow rate and chain tentioner oil gallery are suspects. The oil flow is next to nothing. The supply gallery gets full of sludge blocking nice fresh oil. Same goes for npi heads. They have an orfice, although its high flow, crap gets trapt in the orfice block the needed proper oil flow to feed the lashers. Ultimately causing the lashers to drain out and not pump up. This too would cause alot of noise

Thanks for the response! Guess I need to tear it back apart and check some things out.

And who is to say im right? The problem could be something else, but i do agree with your idea of digging back into it.

Throw a bottle of Auto-Rx in and drive it hard for 500 miles and let us know...

If not a tensioner issue then possibly you are hearing the Fuel injection???

I would dump a bottle of Sea Foam in the oil. Drive it. Change the oil out with Mobil 1 5W30.

I actually did this Fast Lane. After let it run thru a couple heat cycles I changed the oil and added a motor flush. Followed the instructions and then changed oil for the 5w30. After about 20 miles on the car, it's literally doing exactly what it did before. Here's a link to a video of it. RPMs arent being revved not much higher than 2300 here. Really wanting to get this p.o.s on daily status sooner rather than later.

Not sure if this is of any concern, but the tensioners I bought came with a metal plate with a hole in it. The ones I took off the car did not have these so I left them out. Are these necessary?
