It all started with a broken timing belt

[Simion]

Hi Peoples I'm after a bit of advise...I did a timing belt on my VL I think I found top dead centre( both valves closed, piston at top of stroke, rotor pointing to no. 1, 1st mark from the left on harmonic lined up with mark on timing cover) replaced the belt retensioned according to the Haynes manual turned it over had what sounded like huge exhaust leak and not enough power to move the car, took head off, reseated valves, replaced 5 broken exhaust studs put it all back together and won't go. Did computer diagnosis all came back clear except speed sensor cause I can't move the car, can only get orange-red spark from grounded coil lead and spark plug when the manual says it should be blue. Any ideas would be appreciated :bang:

if you broke the belt while the car was running you valves will be bent... time for a new set

ouch, that sounds expensive, is it?

broken valves haha if ya lucky maybe a couple of bent conrods aswell.
id say get a second hand engine or rebuild it cheif..

 

[BIT_SUS]

do a compression test that will tell ya if you bent any valves

PM me if ya interested in a near new head (only 20,000km) or if you want a good s/h one thats done about 200,000. or even if you just want valves i have a head that is cracked that i can pull apart for bits u may need.
cheers

Timing belt broke as the car was started no bent valves, they were checked, no marks on piston tops or anything indicating any strike damage between valves and piston top, will do a compression test today see what comes up.

borrow a friends coil and do a quick swap and see if that changes the spark colour.

I replaced the coil yesterday and no difference, I tested the power transistor and it isn't that either, the crank angle sensor has been replaced a few times over the years but that always shows up on the computer diagnosis test and it didn't come up this time. I've got a spare CAS but doesn't sound like the CAS has gone. :bang:

did you reset the ecu?
