Should I check my HGs while I am in that area?
« on: 05 February 2010, 09:33:25 »
I'll shortly be checking/changing the front and rear crank seals (thanks to andyc for those), timing belt kit, oil cooler, various pipes, and cam cover gaskets.

Several reasons make me want to check the head gaskets for peace of mind and to allay suspicions, so would it not be much of a bother to do that while I have the time and most of the bits off the engine anyway?

Will I have to replace the cam seals? Which other seals should I purchase beforehand?


Thanks
Tom

re-use the old cam seals, they are much better than pattern. Unless you have the symptoms of HG failure, personally i would not bother. Unless its been abused and not had decent anti-freeze mix changed on time, HG should be good for 200k easy  :y

Unless it's showing signs of a head gasket failure I'd leave them be.

It's not showing typical signs but I suppose it is a last resort thing.

The main reason is a loss of coolant I have had for several months despite changing the hbv and doing all the obvious. I even changed the oil cooler which I thought might have been faulty. I suppose it could be a pipe or something.

OK. So you are seeing symptoms that could point to a head gasket.

I my opinion, you need to strip the scuttle, plenum and intake manifold off the car and then pressurise the cooling system and try to identify where the leak is. An old header tank cap with a tyre valve fitted into it will allow you do do this. You'll need to block the two ends of the throttle body coolant pipe though.

Don't go above about 1 bar of pressure.

Ive already done the pressure test when the engine is off (obviously) but can't see any leaks.

No, it's not sat in its own water apart from maybe a dribble out of the AC condenser, but not coolant.

Core plug? Excuse the ignorance but what/where are they?
