Head Gasket replacement

**TheTree** · 11th November 2015, 05:42 PM

The head gaskets themselves look fine so i'm not sure exactly why it was leaking oil and coolant, but the ARP stud kit and MLS Head Gasket should solve the problem

Some pic of the muck around the rocker assemblies

Wondering if this is normal?

HI

That's what I thought, lack of oil changes or lots of short runs to get a buildup like that after 60-70,000 K

Flushing oil should help

If thats the state of the engine, no wonder its blown a gasket.
I'm not sure what gets rid of the gunk thats already there,,
I'm sure a professional will be along shortly

Hi,

The current plan is to remove as much of it as possible then put a new oil filter on, add engine oil flush and run for 10 minutes. Then drop the oil, put a new filter on and new oil.

Then perhaps 5K oil changes with a flush for the next couple of oil changes

Steve, those photos show that either there was a lot of in between short trips ie Sydney suburban traffic and/or not enough oil changes. I'd be putting in a bit of diesel in your oil or some of the engine flushes that are out there to clean it up. It's the sludge that you don't want. It gets into your lifters and blocks them up and not to mention the wear and tear on all the other bits.

After it's all finished, give it a few runs up and down the freeway.

G`day ,

if the pic is telling a true story ?

The bottom rocker face that runs on the stem is well worn as in the stem has burrowed into the face .

If the case ( not just the pic ) i`d be surprised if you slid the rockers along the shafts that you don`t find grooves in the shafts where the rockers run .

Coolant where you`ve found it , on the end cylinders is likely gasket but if in the cylinders and you say the gaskets look ok then block can`t be discounted .

You may like to put up pics of your gaskets both sides and the block surface and maybe someone else may see something missed .

What are you thinking Peter?

Hi

There are definitely signs of leakage from the head gasket, when I said they looked fine I just meant they didn't have any holes or gaps blown in them.

Surprisingly there does not seem to be any wear on the faces of the rockers or the pushrods.

I'll double check the rocker shafts and post some pics of the gaskets and the block later today
