K-line guide liners..

[JLaw]

Does anyone have any experience of these guide liners, good or bad, rather than replacing guides?

Cheers.

Hi i use it, and know that all the top fuel team´s from denmark use k-line, and also JPM sweden. he made the k-line for me.

Thanks,

That's good news. I had been told that using the K-Line sleeves wasn't the 'correct' way and the guides should be replaced but if you say JPM uses them then I'm happy.

Stop being cheap and do the job properly john 

But seriously, liners do sound like a poor alternative to  a proper guide replacement.
Although they do offer a DFL coated version.
I wonder why JPM used them ?

Are you thinking of using some Del West Ti valves along with my 4" cylinders ?

They are a stop gap, but quality kit and ive used them often in heads that were a bit tired of having the guides often removed, split guide bosses happen after all, i also found they suck oil, probably down the join line, this may not be a problem on some uses, i had a blue smoke puff every time i came out a of corner on the circuit cars that used them.

Hmm. that´s weired I/we have use "tons" of them in anything from Harleys to ACVW to V8 engines. I have never experienced oil consumption, yet. The K-lines are stronger than normal guides used in the AC world. I.e. they last longer than a regular guide replacement.
I tend to think that the blue smoke was caused by the rings doing overtime rather than the guides. If it was the guides, the blue smoke should be almost all the time and not just out of corners.

I agree the quality and material is top notch , i ran a 10 race season with the liners installed with no wear,  No ring problems either, Fastback noticed a similar haze on his turbo bus, it gets sucked down into the chambers on corner entry off throttle conditions, some corner entry's are off the gas for 4 seconds at high revs, the right rocker chamber is oil laden on right hand tracks, it then burns off as soon as the throttle is opened, circuit racing shows any oiling problems.
