Wat the hell??!!

[kieran.s gt]

timing was spot on i tripple checked it cos i think thats wat caused the valve to drop, its gt to be those shims surely, wen the cam lobe is up and the valves should be shut theres no clearence between the cam and shim, even if its slightly open it wud affect compression alot wud it not? where can i find the valve clearences?

thanks mate, now where can i get sum shimms from for quite cheap? I hope to god it cures it dunno wat to do if it dunt, but that hurdle will be delt with wen/if it still happens

 

[keya]

so you work out wat size shim you need by mesuring the clearence and the shim and work it out like that?

did all the cam caps go in the rite way and are u useing the maching set for that head ? all valves clearances must be check if ur swaping heads . did u take the service bolt out of the inletcam when u put it back in ?

chris i dont think he put the service bolt in the cam gear prob he never heared of it

i actualy have and did leave it in so it was stopping the cam gear from doing a full rotation!

The heads comming off again and is being sent for re-shimming. see if that cures it, its looking like it should, i hope to god it does!

if it turns over 180 degrees then locks, you must be getting piston/valve contact. are you sure the timing isnt 180 degrees out?

its a non contact engine i thought

well by the sounds of it when the valves where replaced u didnt get them seated.. also seems like shims are mixed up, so their clearances are awol.. apart from that for a piston to hit a valve u need to be really out timing wise...

remove head & check everything bud. also get the head skimmed.

imo id get a new head as sounds like theres alot of complications in ur current one, which being from the uk would kill u labour cost wise..

just my 2p.

its a new head i got it from idrees and its been skimmed + tested i fitted it and then this problem occured, ive sorted the timing out n now its off for shimming + the valves laping (re-seating). hopefully this will cure it. ive saved a lot of labour charges cos im doing it all myself, except the engineering sort of jobs.

 

[keya]

Hi again ppls, got news from the engineering firm, all the intake shims were out of spec, so its getin sorted and re-fitting is gunna commence on saturday, ill keep u guys updated!

New problem has occured, ive built it all back up AGAIN, everythings torqued up cam caps, head bolts, con-rod end cap (no.1 cylinder), just got home and noticed a pretty loud knocking noise any ideas wat it could be?? She just dosent want to get fixed the bitch!! everytime i sort sometin out somthin else goes wrong its doing my head in!!!!

Bump

[weeJohn]

Is the knocking from the top or the bottom of the engine?

 

[Mike D EP82]

would you just be better off replacing the head as there is something obviously not right since it dropped a valve. did you replace the valve guides and seals, new valve seats if they were damaged, and ground them in?

My head use to make a loud ticking/knocking sound a while back, turns out the cam gear wasn't tensioned/aligned properly. After gorganl made a quick adjust it was completely quiet afterwards. He taught me what you need to do, but I have forgotten the details since I never needed to use that knowledge till now

Found out that the big end bearing shell on no.1 piston has collapsed! Its scored and marked the crankshaft so it needs re-grinding! Im thinking im going to buy a forged engine like i should have in the 1st place, that will sort the problem out once and for all!

Thanks for all the help guys!

Rep Added Where due!

Ah mate you really didn't have a nice expierance with it. Rep for keeping the chin up

 

[keya]

thanks mate, bin trying my best! just wanna get it fixed i love that car lol

 

[keya]

Just thought id post an update, i managed to get a replacement engine from nick jones, its in and running whoo whoo! ive also got my wheel back that ended up fooked! all i need now is a re-map and i can drive it in boost, cant wait 2 get the hybrid spooling!

Thanks again for the help ppls, as allways it is much appreciated!
