Fed up

Well I've got the Astra running. It was something silly, just an earthing issue.

As many will know, I removed the head, and fitted all new stem seals, due to it burning oil (blue smoke) when revved after idle.

Well I did a complete job on the head, re-lapped all the valves, fitted proper green stem seals, torqued down the head with a new HG, spotless surfaces, so on....

Also, entire breather cleanout.

Guess what?

The problem is exactly the same.

Let it idle a minute or two, give it a hard rev - and watch everything behind you disappear into blue smoke!

Fed up with this now

had a similar problem recently with a ford sierra(yes really!!)i removed the head 3 times and changed various parts,but eventually i had to bite the bullet and remove the engine.all the piston rings were fubar.

I've decided that regrettably, I don't really have the facils to remove an engine - I'm tempted to just keep putting oil in it.....

Got insurance? Petrol can, match

Is it possible to remove pistons from the bottom? (I Really don't want to have to take the head off again)

sassanach · 18 July 2009, 18:39:40

well the only reason that i simply didnt just change the engine is where do you find one for a sierra?.however you do have that option,get another lump,throw it in the boot and pay a visit to sunny trowbrige where we have the finest engine crane available(fork lift)

I might take you up on that offer Mr Sassanch. I could probably get my uncles garage, but it's a little cramped by comparison.

My only concern would be, seeing as this is so common with these lumps - it's quite likely If I bought another one, it would have the same probs

well removing an engine,re ringing and re installing is quite a tall order for one day BUT not impossible.you need to know if the engine is still standard ie not rebored etc.and yes the head will have to come off again

I agree - I think that would certainly be a bit tight....!!

Maybe more appropriate across a weekend!

must be frustrating

JamesV6CDX · 18 July 2009, 18:56:07

3.0 V6 astra, anyone?

JamesV6CDX · 18 July 2009, 18:57:05

I am beginning to think that, if I had the opportunity to drop an engine into anything, I might pop one in the MV6, and slap an LPG kit on it

Just had a look in the plug holes - tops of pistons all look wet

I wonder if the valve guides might be worn? They felt OK when fitting the valves...

It could be the head is porus or cracked? i know the red tops were bad for them going porus
