PISTON RING/ LIFTERS?

Post by **vipfto** » Mon Aug 04, 2008 6:35 am

Big prob guys

Started car yesterday and she almost felt like running on five cylinders
blue smoke was coming out exhaust periodicaly, I removed the plugs to check them and the rear bank had one that was oiled up
I replaced and still same issue
Now to me it sounds like a couple of things
1. piston ring shot
2. lifter for valve bugered or valve sticking
3. Bent valve
Any more ideas will be appreciated please?

just to note there was some oil (not much) sitting on top of piston also once again that indicates to me rings?

Bugger!

If you rotate the cams such that none of the valves on that cylinder are depressed, you should be able to use a big screw driver to lever them & check if one has seized or bent. To check for a blown ring, you'll need to do a compression test on a good & the bad cylinder then compare figures.

Yeah pretty sure its the rings will compression test tommorrw the valves all seem to be ok
Oh well looks like will park car up while we in adelaide and it will give me two years to plan a 6a13TT transplant
