Losh's VR Ute build thread

Why the heat shield is there in the first place? Why the extra expense? Is actually for heat or is for noise dampening, or both?

I always try to find the true intention of the component before removal and/or modification.

It’s mostly for noise dampening.

Yeah, we had V8s under bonnets with no insulation for years. Pretty sure my Jeep never had one and there was more heat in that engine bay than my V6 ute has. I think they look daggy. They only last a few years before getting dirty and after a few more years they deteriorate.

They only last a few years

Is this the aftermarket one you bought a few years back?

It's been probably less than two years, may be only a year or so. Can't get a gen one anymore. This one is supposed to be OEM spec but I don't think it is. I wonder if it's not handling the extra power, hence why I am thinking Powerbond HD if I can get one. AFAIK it hasn't been off using a bolt puller, which wrecks them pretty quick from my experience. I'm hoping to pull the belt tomorrow and listen for the noise. I will also feel the balancer for movement. It doesn't seem to be running perfectly true all the time. Although a rubber mounted pulley may not run perfect from new, not sure?

Ahh the bonnet mat, that was SH when I fitted it. It was VGC though. When I say they don't last, I mean they start to look ordinary pretty quick. They get dusty and oily and you can't clean them. If you do they fall apart. You can buy aftermarket ones but I heard they don't fit perfectly. Original, no hope of finding one new. When my strut bush broke it put a hole on mine that I sikaflexed, but it looks average now. I do have a pretty good one from the wagon, but it's faded and roads I drive on it won't last.

Based on the pics and what you are telling me. In my opinion, the fuction is for sound suppression.

That’s correct.

The next one is where the roller bearings fail due to wear or lack of oil. This causes the roller to stop spinning periodically or completely and the roller skates accross the cam lobe. This can also happen with low oil pressure as you need sufficient friction for the roller to spin. The tell tale sign of this is the squeak sound comming from the engine. When you hear this you need a new cam, lifters and possibly new cam bearings.

Does this occur when the engine is hot? Mine is making this noise but I only notice when it's hot.

Yea when it gets hot it gets louder.
