Guest LOW'N'SLOW Posted April 14, 2013 Share Posted April 14, 2013 To small and un baffled sump I'm thinking . . . always had it in the back of my mind I needed to make a better sump. Quote Link to comment Share on other sites More sharing options...

Guest LOW'N'SLOW Posted April 15, 2013 Share Posted April 15, 2013 Oh cheers for the offer man!, will strip it down and see what carnage we have Will dig up Freds thread to see how he winged his sump so he could still get the bolts in to fit the sump.

Guest Valiant Posted April 17, 2013 Share Posted April 17, 2013 Stink. I was hoping to see this going. I couldn't say what has marked the head like that, there is a good chance that it was just one item though. I have come across objects that bounce from cylinder to cylinder with out being spat out. Hopefuly it won't cost to much to rebuild. Quote Link to comment Share on other sites More sharing options...
Guest Truenotch Posted April 17, 2013 Share Posted April 17, 2013 Option 3 and keep driving it. 1 Quote Link to comment Share on other sites More sharing options...
Guest LOW'N'SLOW Posted April 17, 2013 Share Posted April 17, 2013 Good idea. can implement few bits in stages and build up parts. Car is getting parked up for 6 months either way, OS nats was always intended as a last shakedown before OE. just wanted to make decision while everything is fresh in my head Quote Link to comment Share on other sites More sharing options...
Guest fuel Posted April 17, 2013 Share Posted April 17, 2013 those marks are from detonation/pinking. Quote Link to comment Share on other sites More sharing options...
Guest LOW'N'SLOW Posted April 17, 2013 Share Posted April 17, 2013 Going to travel with uncle in laws race team. Looking forward to Silverstone and castle combe. Might go to silverstone classic. unsure if Ford fair would be bit to much for for one man. / don't want to make it a car only trip. I'm sure they have lovely buildings and plants too. Anyone recommend anything as must do's in Europe? His toys Bike team he used to have Jentin racing His Lola His Ralt 1 Quote Link to comment Share on other sites More sharing options...
Guest LOW'N'SLOW Posted April 17, 2013 Share Posted April 17, 2013 those marks are from detonation/pinking. Ah really, because it did sweet sweet dackfires/detonation when cold, due to G V5 link i presume? Quote Link to comment Share on other sites More sharing options...
Guest fuel Posted April 17, 2013 Share Posted April 17, 2013 probably more so some bits of the tune are not ideal? ie octane too low, lean spots, too much ignition timing advancement, intake charge too hot, coolant/oil temps too high, spark plug range too hot, could even be running super rich and excess carbon build up is causing the hot spots too.

Guest Truenotch Posted April 17, 2013 Share Posted April 17, 2013 Do you run sequential injection, paired or batch? Quote Link to comment Share on other sites More sharing options...
Guest kpr Posted April 17, 2013 Share Posted April 17, 2013 +1 for it being the tune. need to run a conservative tune for circuit stuff. especially on older ecu's or no compensation. det is load sensitive, so may not be there on dyno. but in higher gears out on the track, you'l be loading it up more and can run into det. plus all those other things fuel said, wont help the cause 1 Quote Link to comment Share on other sites More sharing options...
Guest Unclejake Posted April 17, 2013 Share Posted April 17, 2013 those marks are from detonation/pinking. This.Your head is being eaten. What do the piston crowns look like? Perhaps you need to think about adding some high RPM retard and richening up the mixture a bit to reduce combustion chamber temps at high RPM/load (not that I know anything about turbos) Also: you are probably not far off needing to dry sump this thing IMHO.

Guest eke_zetec_RWD Posted April 17, 2013 Share Posted April 17, 2013 Yea. There's nothing wrong with a v5. It's basic as but needs tuning accordingly. If money allows a g4 allows heaps of safety features to prevent this happening (ign retard, boost reduce, fuel increase by gear/air temp/water temp/speed etc) Put a pic up of all the pistons and spark plugs with part number Quote Link to comment Share on other sites More sharing options...
Guest LOW'N'SLOW Posted April 17, 2013 Share Posted April 17, 2013 Will get closeup snaps tonight. Cant remember Marku, its got 4 of them low Impendence is about all I can remember. Ye god dry sump! Really? I guess G4 is probably a good idea now as needs a tune so may as well get it done on new comp. Quote Link to comment Share on other sites More sharing options...

Aaron tuned it on 95 and said running on 98 should make it safe . . . Def always has fresh fuel too, Hmmm . . . MD60 / G4 or new tune? That would have assisted running the bearings to i presume Quote Link to comment Share on other sites More sharing options...
Guest eke_zetec_RWD Posted April 18, 2013 Share Posted April 18, 2013 If it was detonating it pretty much will run the bearings. Quote Link to comment Share on other sites More sharing options...
Guest LOW'N'SLOW Posted April 18, 2013 Share Posted April 18, 2013 Would detonating discharge small bits of metal to stick into head? Will get more snaps tonight How come no show to nats jase? Hows that pinto going? Quote Link to comment Share on other sites More sharing options...
