kookamunga Posted June 1, 2009 Posted June 1, 2009 well all was going great , was having great fun in the sun untill 4 became 3. pulled over to find my car only running on 3 cylinders and chuffing away like the Flying Scotsman coming into the station. traced the problem to number 4 so popped over to halfords for some tools hoping it was just a loose spark plug. after some hours mostly waiting for the engine to cool down nope the plug was tight. thanks to my new friends george mcphee and son came to dundee lifted the car onto the truck and brought me home. All that's left to do now is take the engine out and pop the head off to see what damage has been done. might be looking for a o/s head if my fears come true.
RA Dunk Posted June 1, 2009 Posted June 1, 2009 have you checked the coil packs or done a compression test before pulling the engine?
kookamunga Posted June 1, 2009 Author Posted June 1, 2009 have you checked the coil packs or done a compression test before pulling the engine? yeah i swapped the coil packs around and still not firing on cylinder 4. i haven't got a compression tester to fit the good old boxer engine but from the sound of the engine it sounds to me like a valve isn't sealing. I think things just got a bit too hot for it if anyone has a compression tester in the edinburgh area please can i borrow it has to be local as my only form of transport just now is the local bus service or my trusted push bike at lease that won't have a miss fire unless i catch a fly in my mouth
kookamunga Posted June 4, 2009 Author Posted June 4, 2009 well the engine is out and head off and opps
cullenmin Posted June 4, 2009 Posted June 4, 2009 Nice Hows the piston and bore looking? I got my head looked at.....I mean cylinder heads looked at last year and beefed them up with uprated inlet & exhaust valves, sourced from zen performance. My valves had worn away very evenly until I lost compression in no.3, also had cracks in the cylinder head castings too, in between the valve holes, Version 4 heads. AWD sorted it for me, may be worth a phone call Rich
kookamunga Posted June 4, 2009 Author Posted June 4, 2009 yeah the boars and pistons are ok the is a slight deposit on the valve seat but think i will be able to clean it up. The other exhaust valve has gone a nice blue colour which makes me think it all got a bit too lean. think its time to go for bigger injectors. was wondering if anyone has a o2 sensor as the threads picked up when i removed it from the manifold, was at nobles but i just can't bring myself to pay 160 plus vat for a new sensor call me a skin flint it you must I was thinking about going for bigger valves but i am hopping the is a 2.5 build in the pipe line so might just wait till that happens before i go for bigger valves.
kookamunga Posted July 9, 2009 Author Posted July 9, 2009 (edited) Well she be up and running again finally. What a nightmare it has been first i got ill so had to put the rebuild on the back burner then when i finally got it all built and fitted a set of bigger injectors (i got about a year ago) i found it was only firing on the left hand bank. traced the fault to stuck injectors, so a wee soak in carb cleaner and the gave them a nice big 12 volt feed till they started ticking again sorted that problem out. just need to save some ready s for another remap for Mr Forrest him self If anything i have learned that if you get a set of injectors and get them sonic cleaned don't keep putting the job off of fitting them. it fells great back driving a car that doesn't know the concept of hills lol Edited July 9, 2009 by kookamunga
