cant you get someone in the know to have a good look before you blow a gasket yourself as its such a nice motor and looks under the bonnet, your probably thinking the worst due to what happened before.

 

what about swaping the leads so that no 4 on coilpack fires no 2 plug?

 

done doug, no different

 

Paul james dose no his onions

 

i know what i can hear.. the engine needs a strip and inspection now to investigate,

and i dont think i can be arsed to do it again

 

no i know this doug, i mean software mapping issue, i wasnt sure if jtech knew how to do this his self or not.

 

Damn .

 

i fitted the same size piston as before, the same size as the rest,

i assumed it would be ok, with a light hone on the bore, and didnt really think to much of it tbh fail me

 

it isnt a software issue, all cylinders are injecting the same ammount and i never had this issue before

 

well must be internal like you say then, we had a zvh that lost all comp on one cylinder and after sripping, it was a valve head broken off, ruined the head and chipped the bore, we sourced another head, piston and rod, gave it a light hone and re-assembled it with no issues, so maybe it depends on how much you honed it.

 

i think my honer needs lighter springs

 

but surely when you gaped the rings it would have been fine?

 

who knows mate, they didnt need gapping tbh they were fine, the others dod so maybe theres an issue

 

have you got pics from the bore again J mate

 

i dont think i took any

i might whip the head off at the weekend and see what i can see

 

What did you gap the rings to and set the bore clearance to.

Mark

 

doug get your book out again

i deffo measured the ring gap and it was correct to the manual, and what cp said in the distructions..

as for clearance, it was all done at the machine shop, but im sure now its to big on cylinder 2.

 

Do you want me to check again lol

 

dont break that car

 

its broken most of the time

 

If you set it to the turbo size this is correct.

Mark

 

ring gap fitted

top 0,4 - 0,65
centre 0,4 - 0,65
bottom 0,3 - 0,6

 

dont break it james its to nice to sell off in bits

 

Sorry to read this James. i cant add any advise that hasnt already been said. Still wouldnt break it though

Sorry Jtech they do nowt for me mate..... stick with your saff or park it up.

 

Id rather find a few more quid and go for a VXR

 

gutted for you james


but to be honest been thinking of an m5 for a while myself

 

na, i want a comfy fast bus.

m5 all the way, there are some fookin crackers on piston heads

 

have a word man!

 

james undoubtedy m5,s are cool cars but they will never give that t4 feeling
give it one more go,you might regret it in the long run as you have the basis of a awsome rs

 

in fairness, your not potentially doing 20k miles a year in a saff which has no suspension, you cant leave anywhere, breaks all to often, and is now the most impracticle car i have ever owned...

so its going

its just not what i want anymore, i dont have the time or enthusiasm to keep working on it just to keep it on the road

comfy, gadget loaded, 400bhp, v8, 180mph, rwd, will do me just fine.
get in, turn key, go

 

your right mate in the fact that doing 20k in a saff with zero suspension is not a lot of fun.i certainly wouldn,t do it either ,my two saffs are for second car use only and as a every day car i drive volvo diesel

 

i used it for 4 days last week, and i could hardly walk

 

but you love 4x4........lol

 

im going to run the 3-door this year,and the saph and see how i feel,cant see me keping the 2 of them as much as i love the 2

lol
what about the service costs of a m5 and if they break do ye fancy main dealership service charges james,

 

I gave up on fast road cars over 10 years ago now, im talking the cosworth variety, but i still to this day would not own anything 'fast road' as there are no compromises between fast, comfy, and nice to drive v economical enough for the daily drive. and i certainly would never own a bmw. hence having rally cars, if it breaks i dont need it monday morning, and they can be reliable, even when driven hard.

you have ruined the car yourself, and i think you regret it now, so break it, its just a car, get your money back and enjoy it ! (just not on a bmw )
