I had slipped timing as spoken about in previous posts. I've re did the valves on the right side of the engine.

The engine now runs but it looks like exhaust gas is coming out of a hose at the back of the cam shaft.

Does this mean a bent valve again? Poorly seated valves? Or a valve guide blown out?

This seemed to happen 3rd time started the engine after a fresh oil change.

Oh I understand now. That is way easier and cheaper than what I was imaging. Thank you so much for the good news.

I can see in this linked picture where he hose should go and what it should be doing with the PCV.

I bought this car seriously faulty as a project to learn. But with missing bits and pieces like that pipe to PCV.

Shall slap on a new pipe or clean and replace the oil separator and PCV valve while I'm there?
 
When I had mine all the bits were there, but I occasionally got a smell of burning oil.

Realised my cam cover gaskets were leaking onto exhaust, so I ventured I had breather issues.

I opted to fit a new PCV valve regardless, that's the rectangular part that bolts to the end of the intake manifold nearest the bulkhead, which is reason I mentioned "assume the humping position", lol.

Unless your a giant you will need a wee hop up step and you'll be kneeling and crouching on top of the engine to do this.

I also discovered that the cyclonic separator drain which goes down to the sump area was split and soft, and probably blocked, it's only about 4mm I/D.

Anyway, I'd be keen to see a vid of your 'smoke', and it would be a bonus if someone with the V8 could pull their pipe off and idle their engine so they could compare the amount of smoke to yours.


DID you fit new valve stem seals?

Regardless, if they were knackered or torn I'd say you would have a smokey exhaust with a distinct aroma of burnt oil, not extra cam vapour.
 
You need a compression test ideally but if you replace the hose and get a piece of cling film or a latex glove , start the engine with the dipstick removed and the hold the cling film or glove over the dipstick tube you should get a slight vacuum effect drawing the glove in slightly. If it is pressured then you have a problem of faulty PCV valve but could also be excessive pressure created by the valve or piston fault pressurising the crankcase/ cam cover.

So a light vacuum is the goal. Failing that replace 4mm tubes and pcv.
 
The pipes that go bad are the ones that are about 20 mm diameter that connect across the back of the engine to the cam cover, pcv and cyclone

The pipe that connects to cam cover was missing, replacement came today. The other large one looks fine I think.

So I had very noticeable smoke coming out of the dip stick tube. So vacuum pressure wouldn't allow that smoke to come out . No need to manometer it up right?

So replacement PCV correct?
