Insane Oil Consumption

i remember reading your thread a while ago about your mystery oil problem - was it intake and exhaust guides that were shagged?

how did you figure that out? was the oil getting past the valve stem seal into the combustion chamber due to excess movement?

Its seems that it was the guides causing an issue. No other problems have been found. It was exhaust side that was the problem so wasn't actually getting into the combustion chamber just straight out the exhaust. Intake side was absolutely fine... :shocked:
 
reason i ask is I think i'm getting the same problem just now but on the intake side....i changed stem seals when I put the head on my last engine, the valves got coked up which i put it down to the bottom end being shot, changed the stem seals when I fist built my new engine and to begin with it was fine, but all of a sudden using oil, but mostly on overrun...I know the bottom ends fine as its only 5k old with brand new parts and im thinking its guide related as they are the part that hasnt been changed....

bloody b series!
 
Pimpin, how do you know it's only the intake side? I thought oil couldn't get into the bore from the exhaust side guides due to the pressure as the burnt gas escapes when the valve opens.
 
well the exhaust side had new valve guides done when the head was built, and I gather that smoke in overrun is a sign that the vacuum is pulling oil past the seals on the intake side....probably going to replace both although going to do a compression/leakdown test first before i start pulling it to bits
 
Sorry to hear this Tim. Was meaning to ask how you were finding life with your B18, hope you get it sorted soon..
Btw, Met a couple at ante natal classes that know you- Joel & Carly. He seems a bit of a petrolhead :) Mentioned he knew someone else with an EK9 & discovered it was you..

As Mr Whiteman said you will probably be looking at replacing the exhaust guides. This was also the exact same problem Bigskank had with his engine.
Get the head off, replace exhaust guides and seals.
Get sump off, big end caps off pop pistons out and fit new rings (Dont mix up big end shells).
Good luck, Dunx
 
valve stem seals wear out due to the guides getting worn and excessive side to side valve play,,

if you only replace only the seals it may cure the problem but only for a couple thousand miles,

B18 is awesome mate, apart from the above issues. So much better power wise.

Haha, small world world though mate. How's your nine treating you?

Will check play in the guides before fitting the seals... if it looks like the guides are chuffed will stop and get the head off to have the guides replaced. :nice:

The only way to check guides properly is to remove head and valve :nono:.
So while head is off you may just as well do the rings :nerv:.

Can't afford all that work at the moment. Going to try the Seals first... if that doesn't work I'm going to have to start saving and take the nine off the road for a while... :(

Tim seriously mate. Sound advice being given here. I know how you feel you want to solve the problem as cheaply as possibly. BUT DO THE JOB PROPERLY! :angry:

If you can't afford it take it of the road. There will be no decent track weather and fun over the next few months as the roads get lapped with salt and grime and it becomes slippery and greasy!

WAIT AND DO IT PROPERLY! Don't take short cuts!
 
I'm not taking shortcuts and I'm not being ignorant with the advice that's being given (the advice has been pretty damn invaluable to me), I'm just investigating the problem in an order that makes the most sense to me.

Lets say for arguments sake it really is just the Valve Stem Seals that are gone and I had spent all the money on getting the head removed and other bits done?

If you guys tell me that it is not possible for just the seals to be worn then I trust your opinions and will seriously consider getting the head taken off.
 
first free check you can do is whip the header off and have a look in the exhaust ports,,

i see where your coming from with taking a systematic approach to the problem,
and you are aware that this approach could end up in doubling up on some elements of the work / costs ,
you have all the information available and your free to make your own decisions,

I'm very much a do it once do it properly kinda thinking person but i also accept that its not always possible,

and problems need to be tackled in ways that suit ones personal circumstances at the time,,

I think he's doing the right thing. I have lent him a valve spring compressor tool that doesnt require him to take the head off so its not really that much of a big job to do if he just wants to do the stem seals.

The way i see it is to start with simple things first, if the stem seals do pack up quick or don't solve the problem then he can look further into it. If he had the head off my opion would be completely different, i'd recommend near enouth a full rebuild. Whats the point in going through all that hastle if he doesnt have to ? What if it is just the stem seals ?
 
Mate I didn't saying you where being ignorant. The cost of taking the head off and investigating it properly is absolutely minimal. Head gasket 40quid and for argument sake a timig belt aswell. You can then check the guides correctly. Inspect the bores for any cracks of damage. The consumption your describing is very unlikely to be seals. In this case I would say as a matter of principle change the guides and seals. Once the head is off anway! That will cost no more than 200 quid. Plus the part above and labour. £500? Now if the stroke kit was fitted correctly the. The top end is the best place to look for you issue. I will happily come down and take your head off for you, so it can be inspected. Free of charge. Aslong as you feed me and fuel me.

There are no quick fixes to oil consumption. All your stem seal will not all go at once. Even one would not cause 50miles to a litre of oil. You have a serious problem somewhere. Please mate for you own sake investigate it properly! Mine has cost me an absolute fortune doing trial and errors! If you don't trust me mate the tx me and I'll send you Will's no. And he can explain it further with you. I'm as pist of as you are with it mate because I know exactly what you are going through and I am only trying to help you in the long run! Do the job properly and thoroughly and it will be resolved and LAST!

I didn't mean it as if you were saying I was ignorant bud... was just trying to emphasise that I was listening to what everyone was saying.

Also no need to mention trust, I think I've known you long enough to trust in your advice. ;)

I'll have a chat with a few mates of mine over the weekend to try and work out where and how much this work can done for. Where's the best place to look for guides, head gasket & if necessary rings to get some prices and give me a better idea of costs?
 
Yeah sorry to say mate but I think your looking at ring related problem there with oil usage that high. Have you had a leak down test done?

x 2 lad

i thought the same and done my seals and it did help but in my case its rings anyway!!!!:nono:
 
I'm sure he said he had to me, both were fine... It could be oil ring related or down to a bad hone still though.
