Head gasket change


Recommended Posts

Hi guys

So as the title suggest I suspect my head gasket has blown.

Throwing code p0356, using coolant but nothing on the floor, strugglesish to start and white steam on cold start. On boost no missfire but at idle and light load it splutters a little.

I think this has been caused by a certain persons misses putting in petrol on the e85 tune and diluted it to around e30 and gave it a little bootfull and drove around for two days like that.

Anyway so Im assuming its the head gasket. Anyone have any tips or tricks to male the job easier or things I should be doing while im changing it?

Cheers

Being organised and prepared will make it easier.

Use freezer bags or little tubs for bolts etc and mark them.

Keep everything clean. Have a tub setup with ample degreaser and a wire brush.

Have the necessary tools close by and make sure your work area is clean.

Have all your parts ready for install before commencing work so you can get it done in one go.

Spend less time walking and more time working in regard to the last two tips.

Did I mention make sure everything is clean?

 

The list of what to do could be quite long depending on what you already know.

 

If the head is off then why not pull it apart and clean up the factory casting?

Port match the intake and the exhaust including the gaskets.

You will have a chance to clean the valves and check the valve seats.

Replace valve guide seals.

 

Beers are important. Drink them when you're done and finished testing. I recommend 12 in 3 hours but your milage may vary.

May be doable in a day with a mate or 2 but its a big job if you haven't done it before. Pulling the dump, turbo and manifold off took me a few hours, you've still got the intake manifold, coils, plugs and rocker to come off before you even start on the head.

 

Can you garage it until you get the box done at CMS? Get it trucked down there and have it all done at once if you can, $$ wise its probably the best move.

If your head is straight and you've done it before, more than once, then one day is doable with the right prep.

The main difference in how long it takes is experience.

 

Match porting is easy mate, you can check google for details. It's not like modifying the internal parts of intake or exhaust ports.

I pullthe head complete and bench disassemble and reassemble.

 

Takes two people to lift obviously.

I've done this and it makes tricky bolts and hoses not tricky.

You will need a wife or mate like Ralph said.

Welll the plot thickens.. no more bubbles in rad and not using water, but still rough idle (literally engine shakes a little) and slight misg at idle and light load. and hearing a knocking sound from the head.

Could timing chain issues be causing this? and easy way to check? 

Sorry for the Derail OP. And good advice puff and ralph

Get the cooling system checked for exhaust gas. Will cost stuff all. 

 

If a plug is fouled from engine juice then it will miss and also not create the bangy bang that makes bubble bath in the radiator hole.

p0356 points to a faulty coil which adds up with the engine shaking.

 

engine shaking exacerbated by possibly flogged engine mounts?

 

lost/losing coolant due to pin hole in heater core?

 

just my 2c on what could possibly be going on here, I'm no expert on diagnosis/mechanical stuff as evidenced in my thread in the 300+ forum however.

Faulty coil/plug

Essentially its a misfire and blaming the coil/plug

And 175000kms old engine mounts haha.

Pin hole in heater core would leave trace coolant.

Much confused

yeah I would be confused too, it kinda makes my cars problems sound less serious sorry!

 

I hope for your wallet's sake it's not a head gasket or any major $ repair.

Cars are bloody expensive!...I have to get the rocker cover ripped off my engine tomorrow for a P1385 (camshaft position actuator) fault code. Obviously 'll get them to look at the wiring to the actuators first.

 

You might have to throw in the towel like I've done and just book it into the mechanic.

Better start checking then mate. 

 

Get the radiator gas analyzed if you suspect the head gasket and the radiator is bubbling. 

 

I paid $25 last time I had it done.
