KH Laser burning oil (sometimes)

Peter B - CV8 · 01-12-2007, 08:43 PM

First post - so take it easy....
My son has a KH Laser, 1.6 litre carby model. It has done about 185,000 k's.
At cold start up, it used to regularly have a sticky lifter tick - but a dose of Nulon "Lifter Free" seems to have cured that problem.
Just lately it has been occassionally blowing a fair bit of oil/smoke - usually when taking off form the lights (after having sat for a minute or so idling). It doesn't last long - just 10-15 seconds then clears up. It also did it once when just sitting idling in the driveway.
I'm pretty sure that its up for a set of valve guides & seals. Anyone else had this problem - or give me an idea of part costs $$ (I'will change them myself as I'm pretty handy & it looks fairly straightforward).
I'm also thinking that the "lifter free" additive was too good & maybe dissolved all the accumulated crud that was possibly sealing up the valve guide previously.

have the valve stem seals replaced

that can be done without taking the head off with
a special spring compression tool and an air fitting for the compressor connection
(sold on ebay )

Going to have a look at it today. Might just have a quick look at the auto transmission vacuum modulator - in case it's leaking. Otherwise I will do the valve stem seals.

Well what do you know !!! Vacuum modulator was full of transmission fluid. It has been sucking fluid up into the inlet manifold & the transmission level was down by about 1 litre (used over 2 weeks).
Picked up a new vacuum modulator for $50- & everything is running nicely - shifts are bit crisper as well.
