Outer Limits 4x4 Board

Has anyone ever done anything to free up a stuck oil pressure relief valve short of removing the oil pump?

Ever since a cracked head that dumped water in the oil (and i suspect a previous owner who thought oil keeps goin and goin) the valves (tappets?) have been really loud (despite 2 clearance adjustments by mechaincs)

Sounds like a hand full of loose gravel thrashing around under the rocker cover.

Anyone got a oil pressure guage fitted, what is the pressure at idle and 2500(ish) rpm?

UPDATE:

Went and got a mechanical oil pressure gauge.
readings are

Idle cold 60psi
Idle hot 25psi
3000rpm hot 61psi
4000rpm hot 69psi

looks to be in spec I guess that answers my question, Cant be the relief valve. Back to suzuki for another valve adjustment.

If thats your rig its a G16b 16 valve the only decent way to set them the valves is hot and is made much easier using a genuine tool. oil pressure wont affect your valve noise, unexperianced mechanics will. Find a workshop that might know what there doing and get them adjusted properly.

Thanks for that, I found a vitara FSM (for later model but still G16b) and it says just what you did. Dud relief valve don't mean noisy valves.

can a faulty

Anyone know of a perth mechanic who actually knows these G16b valve trains?????

Have you talked to any of the below maybe

premier motors suzuki ozzie park
suziwest midland
suzukishop cannington

I go to suzukishop on a regular basis for parts, I didn't know that they do service/tune stuff.

Don't realy get to suziwest, Im Waaaaaay south of the river. I might give premier motors a call.
Cheers

Valve adjustment plus new rocker cover gasket

Premier Motors $150
Suziwest about $120
Suzukishop cannington "the valve lash isn't adjustable"?????????


It sounds like suziwest know what they are doing (having seen 1 or 2 G16b's running B4)

That tells you something about the 3rd shop
Suzuki shop all he realy does is wreck vehicles good if you want parts and thats about it.

Glorious Silence!

The best money i ever spent on any car ever.

Thanks for the help.

where'd you end up going to?
