URGENT oil pressure stop engine

[rich83]

Ahh yes... that a good idea. easy to mark it up on the adjuster too. 

[doylebros]

Im starting to think somethings wrong with the timing, I can't get the adjuster back on! Ive marked it and found a reference point and its got to be less then a mm off. I don't really get it, unless it is on! It doesnt feel like its sitting right though. Im thinking I might line it up so its nearly in, take the cam locking tool out and adjut the inlet camshaft slightl with the wrench to get it in.

Hope its nothing serious!

Before you move the locking tool just put the other tool on the inlet cam to help you first they can be tricky.

Haha thats ok. So adjuster is on, had to turn the inlet cam just a smidge to get it to lock in. Didnt take the tool out just turned it a tiny bit to get it on. Compression test soon

[Pesky jones]

@doylebros exactly what I did and it worked

[rich83]

Good work pesky 

[Pesky jones]

Is 15lbs really only 20nm on my wrench? Seems very little considering how tight the bolt was. I thought it would be around 150nm

[rich83]

its that PLUS a 1/8th turn remember

[doylebros]

It's what Rich say that 1/8 turn needs to be done with a 1/2 drive power bar and cleanly done.

Remember what I told you about oil leaks be prepared to make sure it's nice and clean on top of the gearbox area etc before using the starter.

I was just going to leave it as it is, and compression test by hand?

Wont have time to put everything back together tonight because.I want to do it slowly and like you say clean everything

Wise move - remember to put the battery on charge for your return.

[Pesky jones]

So, compression test done by hand. All four cylinders showed around 30psi. It was hard to tell as I was doing it by myself, and it seemed to change slightly when I repeated them. But all around 30.

Am I wrong in thinking this is a good thing? Am I geyting my hopes up too early

[doylebros]

If it turned that's two full revolutions is a good thing - next stage double check all items you've touched and make sure you've left nothing slack or where it shouldn't be.

You'll enjoy your tea tonight

Compression needs to be built up with the starter turning to get an accurate reading over several quick turns of the engine.You will not get an accurate result turning it over slowly by hand.

That said - 30 psi is very very low, a healthy engine would be 5-6 times that figure

[Pesky jones]

Oh  I had it in my head that 2 bar was roughly right. Perhaps it will be better with the starter motor? Is there any hope in the fact that they were all roughly the same?

[rich83]

Well.... atmospheric is about 14.7 PSI. Mulitple that by the compression ratio of your engine... 9.8?


14.7*9.8~= 144psi
