Outer Limits 4x4 Board

this noise stays even if i rev! it doesnt go away. even if the engine was hot, it still makes the same noise. But it is worse when the engine is cold. and it does get better, but by no means does it go away. it happens through any rev range.

Would anyone one put Penrite HPR 15-60 premium in there tb42 GQ's...? What does everyone use. With a viscosity that is so broad, i dont know what could be wrong with it. or should i just stick with good old HPR30???

i bought a fuel pump for my tb42 for $132. i installed it my self. it came with the gaskets and spacers. Make sure u tighten the 2 bolts nice and tight because they tend to leak if u dont. Use permatex or somthing. Its easy and anyone could do it.

ok well, mine is a tb42. therefore there is a timing chain and there is a timing chain guide, and there is a timing chain tensioner. Leaning towards either a worn guide or some sort of bearing, hopefully just a pully. My AC goes hard and my temp is totally normal. I have had this noise for about 5 ...

ok will do, thanks a lot guys. i'll reply when i have made progress.

its an 88 4.2 petrol engine. done 262,000kms. engine is not over heating at all. we replaced all the belts about 3 months b4 the noise happened. I was on some rocks in low range i stopped the car to go fishing, got back to the car and there was a noise which i thought was sand flinging off the tyres ...

Hi guys, i own a LWB 88 maverick and there is a pretty bad noise coming from the front of the engine. My boss thinks its either a bearing or timing chain tensioner.... it gets faster if u rev,and its really loud.. it sounds like a loud diesel engine. anyone had this experiance or can help me ...
