vk 5 speed is sick pos dieing\

[repo]

hey my vk has lost power pings badly smoking coming out of the rocker cover cant even get 80 kph out of her even if i wind her out it over heated very badly after the thermostat failed to open nearly ceased
go to start her she barly turns over try again say 2 more times she will then wind over fine and fire
checked timing its all set properly all marks lined up at tdc any ideas was running perfect before no smoke coming out of the exust pugs r black but firing well im lost for ideas wife lives the car so gota fix it is it a rebuild maybe head gasket rings

Sounds like you've dropped a valve.

Check for oil in your radiator for to see if your head gasket is gone.

Rebuild time....

[VK SL 3800]

Smoke coming out the rocker cover is normal to a certain extent, what colour smoke? there will normally be a minor amount of white smoke come out, this smoke is caused by blow by - basically compression/combustion gases escaping into the crankcase past the rings, when rings are excessively worn or maybe in your case damaged you will get lots of blow by/smoke.
But anyway i would say time for a rebuild, or drop in another engine. You could consider a V6 conversion or something like that as it may even be cheaper then rebuilding your current engine depending on the going rate fro Black motor parts ATM.

got oil pressure?

[repo]

yes there is oil pressure but the needle moves around a bit with the revs no oil in the water no water in the oil no water loss the amount of smoke coming outa the rocker cover is noticable its white and blueish is running on all six cylnders even idls well as for the starting prob acts like the battery is flat but after 2 or more atmpts it fires like normal was told the windings in the electtronic dizzy could be at foult could this be it

[VK SL 3800]

Is it an EFI 6cyl or a carbie? if its carbie and its original it will have nothing in the dizzy. With the Blue smoke coming through the rocker cover i would suggest it has scored the cylinders and stuffed the rings because thats normally what you see in with extremely bad blow by.
Do a compression test and inspect your sparkplugs for fouling, does it blow any smoke out the tail pipe? Or make any ticking noises ect?

[Tree cutter]

The rings are gone. When a motor gets too hot the pistons expand enough to seize into the bore walls and the rings will loose their tension. If you are lucky you might get away with a hone and new rings. If it got really hot it will need a rebore and new pistons and rings. Its a good idea to replace the big end bearings when you have the engine apart. They arent very expensive.

Mine got redhot, had smoke coming out the rocker cover, wouldnt go above 80 without pinging like a bitch.

This was the result:


Put a hole right through No.2

looks bad its had the dissy replaced with a fuel inject dizzy think time to rebuild her

[ari666]

looks to me like you may have had a phillips head screw bouncing around in there too soz for "pic quoting" but what are the circles on the left side of the piston?

NFI, neither did anybody at work. Nothing in the cylinder when i took the head off, bore was unscratched/marked, nothing in the sump either. It's a fkn mystery.

[ari666]

if you look closely at the impression you can see a little X inside each circle. ill bet a phillips screw was in there at some stage. you can see it getting squished each time cos the X gets larger and larger

How does a phillips head screw get into a cylinder?

[ari666]

via the carby i would imagine

[VK SL 3800]

Could be one of those ones with a swapable end and the little end peice fell down when tightening the carbie screws with the air cleaner off.
