Hey guys got probs with getting vlt to run right. i took it to drags friday nite, had huge lean out and melted all 6 plugs, i threw some new cooler plugs in hoping it would all be ok, no such luck. Still runs the same, idle is ruff as if a plug is still farked.Also have a bad squeak coming from motor i think, doesnt seem to be turbo sound. Now question i have is what damage would i have done? hole in a valve, melted piston? Going to get compression test done and see if thats the case. ive taken rocker cover off and had a look at cam, lobes seem to be all in tact. any help or ideas would be great thanks. Some original photos have not been recovered yet.

Ouch does not look good!! Looks to have run super lean to melt them like that. I can only hope you have no piston damage. compression or leak down test ASAP and see what happens. Do you know why it has run so lean? fuel pump or vaccum leak???

what do the new plugs look like have they melted to ?

mike only ran it for short time,30 secs so it wouldnt show any damage on new plugs. id say the squeak is from part of earth strap down bore!!!eek at worst id say ive melted 1 or more pistons! Matt, i think it was cause by number of things that night, after first run, Ben thought it was running to rich so he adjusted the fuel reg, did 2nd run had same prob but worse, Ben thought it was vaccum leak, so we took manifold off and resealed it, and found back plug was loose,went out for 3rd run was the big bang, went so hard off the line and pulled hard, seemed to be running sweet, but half track she went ruff and the rest is history!

they always go good before they blow up. id say shes fried some rings.

yeah il say its put a hole through one or mare valves,hopfuly its not a piston,but it could be,couls of damaged the pistons.the ends of the plugs have to go somewhere,............throught he motor them through the turbo etc etc,

Sounds like you might need to bring down a trailer to pick this engine up lol

sorry to hear that man. possibly may have melted the top of the pistons putting the piston out of shape and making the rings not seal

If that engine isn't dead your a lucky lucky man.. Next question why of why would you touch the reg? Stock ECU etc isnt it?

poor DOSE IT

Stock ECU etc isnt it? hey man, yea stock ecu. i put a rising rate fuel pressure reg, 1:1 ratio.had it set up right before went down there, my own fault for not getting it tuned properly but oh well live and learn. Mate who came down to drags with me is a spanner thrower and had a play with it as he said while going down strip it was blowing black smoke.So he adjusted it.id say hes mis judged it or other factors played a part.its done now so meh. time to build up a stronger motor and get it tuned.

Thats it bud, it always gets bigger and better next time Lessoned learned though and good luck Some original photos have not been recovered yet.

you said the same to me that mine was black smoke at drags (easy to think its rich but its probly just the tired engine showing itself) so ive leaned it out, now its got lean bog and wont drive lean is ok but it kills VLs have just adjusted things this weekend and its sweet as now sorry for your loss Kelvin your best to pull the head or swap engines

oh really, sorry to hear that bout your car Dave, yea easy to mis judge things eh. wasnt meaning yours was running rich when i saw black smoke, was just letting you know what i saw, least you caught yours in time by sounds of it. yea will be swapping heads and replacing the slugs if need be

kelv my bro has a block all cleaned up at home standard bores. shes ready for oil pump pistons etc. if you wana do that let me know as its just sitting in dads shed.dad may even put it together for you. hes doin a 308 and a 383 for a couple of guys at the mo if you're not in a hurry.

Is that the block that I sold you way back ?
