all aspects of race car design, mainly engine blue printing and design. am a coded weilder, and have much experience in body work, window tints, car electronics and also heavy goods vehicles systems like air suspention and air operated systems. i normaly use angalsy race course, as its one of the closest to me. i love jap cars and own quite alot. av bin to JAE the past 5 years, and many of the jap car meets at santer pod.
also whille this subject has comup. the forged rods with the grooves provide much better oil breakout from the crankpins (replenishing) and lubricate the thrust surfaces much better reducing frictional losses and reduce shell to pin radius ride. xx
colin get face book and com on our page unit 6 motor sport. all our engine get stripped and all info put up thr for all to see mainly the toyota engines and honda. we have built a d15y8 engine at the min that should be amazing. its got the 3rd compression ring (good for boost) and a very good crank to rod ratio. a t3/t4 turbo is going on. should make the b18 look tame. xx
the big end and even thrust clearence of the conrods and main caps (crank) is lubed by oil breakout from the shells the only part of the crank that might be subject to splash/misting will be the little end but thr is a oiler hole on all e serise con rods. so this is now not the case. misting is not desirable in pro engines. just in its nature it increases crank case pressure (not good).
and to answer the question asked here it simple. or at least could be = heat and piston ring sealing. expansion of the piston due to inaficent heat removal of the bore walls and rings = (runin process). or seizer of the little end forcing the crank to have to force the rod round = conntact with the crankpin and shell.
luk is right guys. i can put up direct pics of the main oil gallery from the oil pump to the oil pressure switch. cant belive wat im reading. splash to feed your big ends "crazy talk" even the little end whitch in som cases can be fed by splash on the 4efte is fed by a hole in the con rod called a oiler. this require pump presure behind it to do its job. com pn guys this is basic stuff.
u the man, now we talking proper power and u can tune this motor like u would not belive. proper petrol head. chris and holy crap thats tighter thn the corsa.
u got it in 1, wat was ment is thr is loads more thn just unbolting and rebolting. i do mine in the kitchen, the dish washer cleans things a treat. hehehehe chris. xx
just watch out for bangin it thy very delacat. thats the problem with fitting thm under the car if it takes a nock i always fit on down pipe if poss, warms up faster and does not tend to soot up . chris
gutted sparky, engine building is a fine art as im sure u know. welcome to the wonderful world of motor sport people. chris. p.s makes me laff wen i see people on u tube building thm in thr sheds.!!!
