Add to that! If you don't have the original airbox then simply remove the induction and see if it improves, nothing on the throttle body will be fine. Just don't let any flies or dirt into your TB :p
 
Hi mate,

Thanks for the input, I know (y) i was planning on replacing it after head transfer, just all money has been diverted into trying sort this out,

Flies wise yea lol there's loads of wasps around here hehe

but on a serious note lol, I have tried it with the induction kit off and no difference mate. (n)

Take it off and give the throttle body a real good clean then go rag the hell outta it with some redex in the petrol! See if it clears it out. Chances are the blocked filter not letting enough air in. Overtime you'd have gotten carbon build up in the pistons and dirty throttle body.
See how that goes! Best bet and cheap to do!
 
Good idea (y) but I've had this on for a good few months even done rhyl and back around 6times on this setup on old head, and never this trouble,

Just seems abit odd this start now? and even without induction kit mate it still runs the same, ive give it welly at idle without it and it doesn't help in any way, engine still stumbles and misfires, sorry be negative :(

last time hg went, after fixing it with that induction on, first turn of key it was purrrring well apart from the knocking on camshaft, but exhaust was steady puuurrrr :cry: i miss it.

ps the pistons were left silver clean before other head went on. they did have carbon build up, even doh the valves and stems were white?

Would have been clean because it was burning coolant. Carbon build up is over time. 100 miles. 10000 miles. It builds up untill it hits! If the timing is definately fine I really do think its this. You could always take the head off and see if there is build up but it's just as easy to do what I said
 
i will try it, but i can honestly say before the transfer the hg was perfect no coolant loss etc no signs of dodge hg, the only reason ive distured the engine is to change the head because mine was kncocking on the camshaft that's the only reason, due to bearings by the looks of it, but i'll try it (y)

I'm sure HG is fine but I bet your pistons are coated in carbon and throttle body dirtied up

pistons must be by now mate, as my spark plugs not even a week old :bang: have got black carbon sutt on them all 4.

i've had the throttle body off since, yesterday in fact to make sure it was all sealed ok, that so far is still clean yet.
 
If you want it perfect. Take the head off. Clean the pistons by hand. Get that induction off or replace the filter bit. That will keep it good and if it goes the same again THEN you should start looking for causes but I reckon it's all down to the induction.

I'm sure I blew my head by induction being crappy, overheating and pushing the car too much

causes mate lol i've ran out of things to try, however what your saying is true, maybe thats a reason my fan kicks in too early aswell but thats another story. I will get my standard box back from dads tomorrow put that on and see how it goes, just don't want to keep running her in fear of destroying my cat :cry:

that would just finish the car off, as the other half is now sick of spending on her, wimen! yet i wont give up :D which kind of creates arguments lol

another thing too mention, id understand this if i drove it the way chavs drive there's, rough! but 95% of my driving time I drive with my 2year old daughter in and 24week old pregnant partner so I drive almost like a granddad lol just too be safe.

If your driving like a grandaddy then than causes carbon build up! At this rate you'll pull the head off and have a perfect cylinder shaped block of carbon! (y)

Give it a clean, sort the air intake out and rag the ******** off her! It's just like a woman! Loves to be ridden hard once in a while (y)

Everything points to it!

lol yea cheers. ok so maybe not that bad, if i need pull off fast etc i do just not very often (y) but am no way like a sunday driver ggrrrrrr lol

I'll do as suggested so thats been tried, and let you know what happens if anything :worship:

Yea if only she'd let me :devil: lol
 
ok peeps jst been looking at sum pics and u can see the head ive put on is smaller. what do you think?

1st pics are my old head, 2nd are this head.

i swear my heads fatter/bigger

also my old head as markings 29B. which the head now on just says 28.

could it be warped with it not being skimmed and sucking in air somehow?

That oil is from the cam cover its too high up to be from the head gasket (leaks flow down not up).

Take a sample of coolant and have it tested for combustion products and petrol. Any good garage can do the test. If it contaminated the HG has gone.

You've also not confirmed the O2 sensor is any good. If its shot the engine will run rich and roughly.

(y) I know mate the 2 top pictures are from my other head around a year ago, and the bottom 2 pictures are the engine now, uploaded because between the pics there is a size difference in the heads.

And on a previous message ive put a different o2 sensor in, its made no difference, engine is still the same no better no worse. so can take the o2 sensor out of the puzzle. along with all other sensors in the car they are working. I believe it maybe a mechanical problem, I didn't have the head skimmed? have I been unlucky.

Also bredsticz mate, I have the original air box and new filter on now, and no difference after 14mile of driving, heavy acceleration.
I have noticed a smell coming from the exhaust as well when the engine is hot, not rotten eggs but doesn't smell pleasant.

Me thinks this head is dodgy warped/cracked maybe? maybe get a 55s head try that. plenty at scrappy and on cars between 40k-60k, maybe look for the condition of the spark plugs in the scrappy engine see if there tan/light brown, check the cam lobes make sure there silver and shiny, unlike the cam lobes in this head dark brown. and also check the cam bearings for wear?

Driving like that for 14 miles won't clear anything. It needs cleaning out or redex in constantly and driven like that for few 100 miles.
If you're changing the head take a look at the pistons, give them a real good clean

Okis matey, well im not going push it for 100miles sorry, this funny smell coming from the exhaust when hot is kind of concerning me as the cat maybe suffering from the engine. If that dies bye bye car.


Will do head wise, any tips for finding a good head at scrappy? When sorted the valves in the next head will have the treat of being cleaned and reseated.

And I better make sure it get's skimmed this time!
