Out of interest just because I'm wondering, can a failed or broken lifter on a 3.2, only create a noise when hot?

[symes]

 normally if lifter fubar its continues from start- But being a miggy anything is possible

[omega3000]

Mine did it from cold , slightly less noisy when warm but still noticeable 

[tunnie]

It's other way around on the 3.2, sounds fine cold.

Oil pressure will be lower once engine is warm. If it's too low the lifters might start rattling.

Lifters tend to be slow to fill from cold or collapse completely.

Haven't we been here before and measured the oil pressure?

Yup, was inconclusive though. I know it's been agreed its fine to just live with it, but it bugs me

Back to oil pressure switch, was hoping things might have changed and become an easy fix 

[Kevin Wood]

How low was the oil pressure? Can't remember.

[albitz]

If you need lifters ? theres a set of 2.6 lifters on ebay at the moment,which I think would be the same ?

20 PSI from when I did the tests:

Oil pressure switch is a 5 minute job unless someone has damaged the thread or split the oil pump casting.

Swapping the oil pump involves removing the front pulley which is held by a bolt done up to 250 ft/lb. Easy with a 5 foot long scaffold pole & something to prevent the flywheel from turning 

Seem to recall some talk of mother T's car having a split in the casting 

[tunnie]

Bah sorry got my terminology wrong, I meant oil pressure release valve thing, the one were the belt has to come off. Had the pressure switch out easy to check pressure

MotherTs never had a split in the casting? Her V6 goes well

[Kevin Wood]

I think he means pressure relief valve.

TBH, 20 PSI ought to be OK. If you want a comparison with another 3.2 (with 142k on it) I'd be happy to check mine, if the gauge is still around?

It sounded like pretty much all of the lifters were rattling to me, which kind of rules out a faulty one in my mind. Might be worth getting a replacement set, refurbing them and just fitting them to be done with it?

Only other thing that occurs to me is that maybe it has had the heads swapped in the past and the combination of lifters, T vents and oil pump is not one that work properly? IIRC, it looks fairly original, though, and unlikely that a 3.2 will have had major surgery at 140k.

Gauge is I think in same place in the garage, will check 

Will keep an eye out in breakers section, for a set of lifters. It all looks original & unmolested, the NCDC unit still had its warranty sticker on it 

As pressure is decent enough, also never really heard of low pressure issues with any of the V6's - Maybe a set of lifters will sort it out 

[feeutfo]

I can't remember exactly what work I did on that engine, plugs and belt I think, but in the corse of doing so, it was fairly obvious some gorilla had been in there before, coil PACs looked like they'd been removed with a hammer and chisel, and almost every plastic clip and fixing broken off.

But did I see a bolt missing on one of the heat shields? Or was that on another car?

Could not see them?

Think all later V6's had same lifters?
