Thread: 3.5 V8 freshen up suggestions

If you're opening up the motor, replacing rings, big ends and head gaskets at the same time won't break the budget. This is easy enough to do in vehicle if you're working with limited workshop space. Add a valve clean/grind and new inlet stem seals. Head gaskets are a common enough failure at 200,000 to 300,000km so worth putting new ones in. You also get to clean and inspect all the bits that produce the power.

With around 300,000KM on my 3.5 I started to run into low oil pressure issues when the engine was warm and idling. It might pay to look over the oil pump/clearances to make sure you have tip top oil pressure for the new cam.

Cheers guys,

I'm not sure how many km's the motor has done, the odo that was in it showed 34,000km when I got it but who knows how many times its been around the clock.

I was trying to avoid rings etc, the way I look at it is that it's not blowing any smoke and the compression is good so the rings shouldn't be too bad. I also don't want to go down the path of honing or boring the cylinders which I would want to do with a new set of rings. I'm not looking to do a full rebuild, just a freshen up.

Good point on the oil pump, definitely worth a check although the motor seems to have no problem with good oil pressure. New stem seals are a good idea too.

Cheers,
Steve
