My vr smokes from 4.5k up

[smarkham 0]

Just had the top end re built about 2k ago. Now its smoking from 4.5k up even with no load. Is this rings or could it be something else. It never smoked one bit until the re build. If its rings what sort of cost am i looking at for a bottom end re build ?

Sounds like the head may need to come back off but I have known for blocked breather pipes to cause this sort of thing but can't believe they would have not checked after having the head off and replace stem seals and guides etc. Another possibility is that the oil pressure relief valve might be at fault. I would check the oil pressure first, should be at 29 psi at 2000 rpm and also check any pipe work for blockages.

Yeah thought about a breather I took the one off the rocker cover and i didnt help. It had a recon head was thinking it could have been a bad recon job. Is there any other pipes i need to check ?

What Colour is the smoke Black or white? If it's black then it's a Fuel thing. The main breather attaches to the cam cover, thats the one thats needs checking. Also the unit it connects to. I would have the oil pressure checked.

Definately oil then. I can check the Bentley for you and see if it gives any indication.

 

It shows that there is also a relief valve between the block face and cylinder head, if they got crap in it when the head was removed it may have clogged.

Well just got it compression tested and all looks ok. They think its pulling in oil from the rocker breather as all the plugs had a bit of oil on them. Come to think of it I replaced the pipe 2 weeks ago as the old one had a huge hole in it. Going to run it with a breather filter for a while to see if that helps then go from there.

Good luck with that.
