Reply With QuoteChecking for flatness is mandatory, I don't know how stiff your steel ruler is, some are a bit floppy or crooked. You are looking to grip the thinnest feeler gauge anywhere across the head, i.e. flatness within 0.002" or so.

Ok, so after a plethora of things has gone wrong with Stacey's Pajero, the head gasket now appears to be gone aswell, well at least one of them has.
I am in the process of slowly stripping everything off the engine so i can get to the heads and take them both off. Is it a mandatory thing to have the heads shaved (what ever the term is) when you do head gaskets? Or can I check the surface of the heads with a steel ruler to make sure they are still flat and bolt them back down at the correct torque settings with new gaskets?
Thing is we will be selling the car soon I dont want to spend unecessary money on the car. Having said that I want to do the job right so if they need to be done then I'll get the heads done.

It's not manditory, but a good idea. Shaved, surfaced, same thing. If you have them surfaced you can also get them crack tested, a real good idea if it has been hot.
If you don't like trucks, stop buying stuff.

Thanks guys, the engine hasnt been overheated or anything like that, the gasket has just let go and the engine is using coolant, coolant isnt dropping on the ground and the heatcore leak seems to have been sorted by the bars leak. There appears to be a bit of oil mixing with the coolant aswell.Originally Posted by V8Ian
I bought a 60cmx40cm steel builders square today, figures it might be a bit more rigid and accurate to check the flatness. I have a set of feeler gauges so I'll give it a good check before i decide.
Any idea what it would cost to get 2 v6 cylinder heads shaved, provided thats all that needs doing to them.

If its only that much, i might aswell get them done.I just has my V8 heads done for $80 in folding.
The manager of repco tells me there is a guy out of town that does the work from his property, its a bit of a way but he is supposed to be the best guy in town, i might look him up and give him a call.
Thanks Ian.

Well, got the heads off today, both head gaskets look to be buggered, starting to de-laminate and the bottom side of the gasket was well and truly stuck to the head, a fair bit of the gasket was left behind when it came off.
Looks like the heads have been done before and Dodgy brothers incorporated put them back on. There was a nut missing from one of the exhaust manifold bolts and the whole passenger side wasnt done up tight.
Spoke to an engineering place here in town and they can do each head for about $8o the pair. It looks like one of the heads has been welded before so im going to get them checked over for sure. Bores are in good condition which is good.
Once the heads were off i got stuck into the heater core, stuff me what a job, total pain in the arse. I hate working on dash boards.
