Just had a long awaiting chat with him over the phone!! I think it maybe the leads, he's gonna change back to sturdy originals and check again.
Right - I had a poke around last night - swapping plugs, leads etc. All cylinders appear to be firing, but some more than others... i.e. if I remove a lead from the coilpack, the engine will run rougher... but with some cylinders it runs a lot rougher than when removing others. The cylinders that dont have as much impact on running when removed appear to be 1 and 5. Those two cylinders also have wet spark plugs (oily), with cyl 5 the plug was also very sooty and smelt of petrol + oil. All the other cylinders appear to be igniting without problem - the spark plugs were looking good after running the car up to temp. Fuses looked ok, couldnt really tell if the relays were ok. No mayo in the oil Water looked clean Engine is generally oily, so cant really tell if head gasket is seeping out the sides etc.. Looks like I need to conduct a compression test and get the bugger on vagcom. Im busy this weekend (dedicated time off, holiday at home doing NOTHING all weekend). Gurds - does the compression tester work? Last time I remember the needle on the gauge was stuck at a high reading? (unless it is supposed to be like that?) Nav - mind if I borrow your vagcom/cable during next week?
erm... yeh. it got fixed... Thanks Nav! I think Im having trouble getting used to six cylinders. All my experience is with four cylinder engines. Lets just say it was 'engineer error' Did you know.. The word "Assume" comes from the latin words ass, u and me, and, according to ancient scholars, its meaning, roughly translated is "to make an ass out of u and me". Lets just say I 'assumed' I had the HT lead/coil pack connections correct. My bad... So - once we sorted that, we ran compression tests on a cold and hot engine... and Vagcom for error codes. Error codes all appeared to be related to me pulling out plugs while the car was running to see what happened. Once they were cleared down, they stayed away (yay!). Compression test was not bad (considering the rings on cyl 1 and 5 would have been washed down with petrol). I'll post the details on here later when I find the bit of paper I wrote the details down on.
Shame it's not heavy on the hands. Might have pushed the leads into the plugs. Never fear the heavy hand turned up and sorted.
Im waiting to see what you're heavy hands have broken/tightened shut this time... only time will tell!
I found my bit of paper with compression ratios First run was on a cold engine. Second run was after just letting the engine idle till the water temp was sat steady at 90, and the oil temperature was 64 degrees (dropping to 58 by the end of the testing). Cylinder 1 10.75 bar cold 8.75 bar hot Cylinder 2 11.75 bar cold 9.75 bar hot Cylinder 3 10.5 bar cold 9.5 bar hot Cylinder 4 11.75 bar cold 9.25 bar hot Cylinder 5 9 bar cold 8.5 bar hot Cylinder 6 11.75 bar cold 9.5 bar hot I’m guessing the un-burnt fuel in cylinder 1 and 5 washed the rings clean of oil while I was running the car trying to figure out what was wrong (I did run it a fair bit with the leads the wrong way :0s). Cylinder 3 was the cylinder for which the plug was blown off the coil pack, so again, that would have had un-burnt fuel washing the rings out a little till I replaced the coil pack. I’ve been driving the car to/from work for the past few days, and I can say it started off feeling ever so slightly lumpy on occasions, but after a few days of mixed driving, it is feeling nice and smooth again (touch wood). I’m guessing oil has had a chance to fill the rings again? I have noticed a ticking/tapping noise on idle, however I can only hear it inside the car (fan switched off, so its not that) but not when I’m outside. Hopefully it is nothing.
Ever so slightly lumpy? The leads can't swap themselves you know I'm sure its fine. Now enjoy it Gurds
lol, when I said lumpy, I meant it didnt feel as smooth on idle - minor engine vibration coming through... but after a few days driving it has gone. Feels smooth now. Fault codes - no hurry. Im hoping they were just related to me messing around while the car was on. I doubt they'll reappear, so Nav - carry on scratching.
Right finshed scratching. Here are your fault codes 00522 Engine coolant temp sensor. 27-10- Implausible signal intermittent. 00533 idle speed regulation 14-10 Adaptation limit. (add) exceeded intermittent 00268 solenoid valve 6(n93) 28-10 short to B+ - intermittent 00553 Mass air flow sensor (g70) 31-10 open or short to ground internittent 00524 knock sensor(1g61) 29-10 short to ground intermittent 00518 throttle postion sensor (g69) 30-10 open or short to B+ - intermittent 00515 cam position (hall) sensor (g40) 30-10 open or short B+ - intermittent I think the problem is with the driver of the car. He's tooooooo used to driving a Honda.
