not just yet... ive got the parts to fix it but work has been hectic.. im hoping to get the head back on this weekend if i get time and the weather holds out... i have a brand new crank pulley however the bolt is no longer available from fiat so a dab of black loctite on the old one is going to have to do this time round...


pics need to be uploaded and progress needs to be made... however it will all be updated on here when all the niggles are ironed out

You posted on Facebook how and why it broke but you havent on here. Feel like we're missing some pieces and demand updates!

What we are essentially trying to do here is public shaming to trigger progress

your all wrong

lmao... ok so no pics but im sure i can explain.... ish...

so basically after a thrash down the bypass.. late at night and just really trying to work out what the 0-60 times were.. first run after warm up... 2nd gear launch on 0.8bar of boost... i get to the speed limit of 70mph... (obviously as thats the max speed limit right??) let off the throttle and all is fine.. a few seconds later i get popping and backfires.. eml light.. and no power...

so i manage to coast up the hill and into the layby... where it grinds to a halt... i turn the key and theres what sounds like no compression... so i figure it must be a catastrophic hg failure.. however... no coolant and no oil contamination... so i get it recovered home and leave it be for a few days.. order a new head gasket set and bolts.. a new oil filter and get some new coolant..

mid week i decide to strip the head off.. strange... headgasket is fine... like... 110% fine... hmm... rings... so i fill the bores level with the tops of the pistons full of oil... nothing.. oil does'nt disappear... so i grab the TRIGGER PULLEY (cheers woj ) and it comes off in my hand....:bang::bang:

so here comes my explanation/excuse

basically when i was mocking the engine up on the stand i realised the original crank pulley was dented so i removed it and replaced it with one i had on a scrap 1108 that was on the drive... however... the one on the drive had a seized bolt so i decided to hack the head off of it with a grinder... that kind of buggered the pulley slightly but i figured i would replace it before the engine went in.... yea i forgot to replace it... therefore when i tightened the bolt to torque it didnt have a flat surface to mate to.. in fairness it lasted 600 miles of abuse before it came completely loose and snapped the woodruft key and then falling off..

so theres my explanation.. ive now ordered a new pulley from fit.. i have all the bits i need to get it all back together now i just havent had time to put it all back together.. hopefully ill be at brooklands this year if i can get a day odd between then and now to put it all back together and get it motd and tracked up ect

watch this space.. pics next time... maybe ;P

cheers

Try some high strength thread lock on the crank pulley bolt as a back up.......

That was the plan to begin with i just totally forgot.. the pulley should have never gone into service.. it was just there as it was better than the one that was on it.. the brand new pulley and a touch of black loctite should sort it for good.. also aparently there is a holding tool for the pulley that will help protect the woodruff key when the bolt is tightened so im going to look into borrowing or favricating either the correct tool or something thatll do the same job

okay so here we are again.. 6 months later and the cinq currently sits.....like..





because i was driving like a bit of a hero .. i managed to hit the brow of a hill (going waaaaay to fast).. successfully launched the entire car into the air.. and bottoming out on the way down, this in turn well.....





so as i already knew the turbo mani was a weak link as well as the downpipe, so ive now ordered a new stainless sch10 thick wall pipe manifold with 12mm thick flanges so hopefully this one will be a little stronger as well as flow a little better

id like to get the cinq on the road for a few months and then the shell will be going to scrap, ready for the new cinq which should be with me in the next few months

so the reshell begins.... ill add the link to the new thread below

Said linky... the build continues here
