Stuck at the side of the M25...

And onto the trailer..



Well driving home around the M25 last night car gets horrid missfire so I pulled over. On road side inspection, a spark lead had come off (ok so I can cope with that) but it sounded much to than that) , even when reconnected the engine would not idle, and the turbo was much much hotter than I would have expected (I had not even been thrashing it as it was to wet to mess about). First ideas are headgasket or piston failure. Most likely to be the first one. The cause most likely 2 and a half years of abuse and lots of turbo pressure. But that aside, something certaintly didnt sound in good shape and I'm worried that unburnt fuel and air passing into the turbo was ignited by the heat and has possibly damaged the bearings of the turbo as well, it would have in effect been working as a jet turbine does, thats the only reason I can see it being that hot. I have seen it hotter, but not when I was being as easy on the car.



I guess first of all I shall do compression test, but I may not even bother depending on how the spark plugs look like. Then turbo removal followed by top end strip down and inspection. This should be fun, its the only part of the engine that I have never had to go into. I cant wait.. :(



Oh well, may the fun commence. I may keep a basic progress report here. Ill see how it goes. If it turns out it will cost me a total fortune to fix, then I may just put it in the garage untill I can afford to fix it and get this other K10 I have sitting here on the road.



So once again, if you ever consider getting a march - dont. They are fun fast and origional but they are not suitable as a main car

Been running as an anti lag then (although you shouldn't need any with the supercharger)? Has it felt better off the line just recently? Just before it went bad?

No not really. Its been spot on appart from an iffy ignition lead that i think is the root cause of all this :( :( I've just done a check, cyl 2 and 3 are not working. Sparkplugs 1+2 and

4 are fine sparkplug 3 is totally screwed and looks like one of those horror stories from the pics in a haynes manual. It looks like it was an ignition fault that has killed my engine. The headgasket is without question fried. I know this as there is no compression on cyl 2 and 3. But all the sparkplugs except for 3 look perfect.

I just REALLY REALLY hope that piston 3 the block and the head are not terminally damaged. I wont know that until after the weekend.

Take out sparkplugs 2 and 3 and the engine runs lumpy but smooth and quiet, if you know what I mean. I'm concerened as there seems to be alot of crankcase gases being generated. possibly from a piston blow by :(

ARRRRRRRRRRRGGGGGGGGGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH :( :(

Would that blow by be piston gone, or knackered rings?

Don't suppose it makes much difference in the grand scheme of things as you are probably going to have to do a tear down to see what the problem is anyway.

bad luck mate :(

just had my big end bearings replaced and new piston rings so gotta go easy, fancy racing your micra with me now? :) gimmie a fair chance

I don't know if I can afford to but I may go all balls out on it, and go for a total rebuild. In my ideal world I want to flow the head, get new pistons with a with a slight overbore say 940cc and build the engine to

200bhp capable, possibly drop the compression ratio to 7.5:1 and also build my own improved pipework system, who knows, if the engine has to come out, then perhaps it will be bye bye aircon and hello front mount intercooler. All this with 1.5+ bar boost should easily pass 200 bhp. Also gives me an excuse to change all the rubber mounts now that are totally screwed. Hmm nice full rebuild. If only I could find the money...
