wlaidlaw Posted September 27, 2013 Share #5561 Posted September 27, 2013 Advertisement (gone after registration) I thought it was not side valve, as there were no plug leads coming out of the top of the cylinder head, as there usually are on sv engines. I presume they are hidden underneath the warm intake air cover. Thermo-syphon cooling is where the manufacturer has been too cheap to fit a water pump and the cooling depends on hot water rising to the top of the engine and then cool water falling to the bottom of the radiator. It's never a benefit to have this and calling it the wonderful pseudo scientific name of "Thermo-Syphon" was a triumph of marketing over engineering. Here is the next car - the red one being worked on. We all had a small giggle when its bonnet was constantly up and said: "well what would you expect." Not really very fair to the car, given our problems of the day before, where we had to re-attach a drive shaft to the transaxle, when the bolts failed.

wlaidlaw Posted September 28, 2013 Share #5563 Posted September 28, 2013 Correct Dunk. The picture here is as much as I got of it. The poor chap was having all sorts of problems with the Lucas (Prince of Darkness) fuel injection delivering far too rich a mixture. Unlike the Lucas rotary system, where it is very easy to lean off the mixture a bit, you need a special tool on the inline system to do it, so I could not help him. He had had the system all rebuilt about 18 months before for a similar problem but the people who did it, had not told him that with modern lead free petrol you HAVE to add two stroke oil to the fuel at each fill up or you will wreck the pump in very short order. Modern fuel is very "dry" and provides virtually no lubrication to a mechanical pump, so he has probably ruined the pump (again). We use synthetic two stroke oil in both our mechanically injected cars (Mercedes 280SL Pagoda and 911 2.7RS) and have no problems with them. The 280SL has done over 100,000 rally miles on its original 1970 vintage pump and only now is it going off for a rebuild, when we do the whole engine. You do however need a sympathetic garage when it comes to MOT time, as the oil increases the hydrocarbon content of the exhaust. Wilson Welcome, dear visitor!

Best wishes dunk Not precise but a typical fill up would be 50 litres and we would add around 25 - 40 ml of oil. An alternative to two stroke oil would be Redex upper cylinder lubricant but that is getting difficult to find. We found an ancient can of Redex in the boot of our 300SL Roadster, so this is something that people have been doing for some time. Wilson 1 Link to post Share on other sites More sharing options...

The answer is no Have to be more specific because the Skyline GT-R models were in production for 8 years, had a straight six engine, and production ceased in 2002. But you're warm ... very warm.

WOuld there be any point to adding two stroke oil to my 420SEL (1990)? I never have, and I assume that since the advent of no-lead gas predates my car, the fuel injection system was designed to require nothing but high-test gas.

I never have, and I assume that since the advent of no-lead gas predates my car, the fuel injection system was designed to require nothing but high-test gas. Michael, Not needed. You really only need it where you have a mechanical piston type pump or rotary distribution unit. These were originally designed for diesel fuel, which is obviously far more lubricating than any petrol/gasoline. Years ago the tetra-ethyl lead that was added to increase the octane rating, also acted as a good metal to metal lubricant for mechanical pumps, as it forms a film on both metal surfaces. However even then, adding some oil was a good idea. Some people think that if they use LRP (Lead Replacement Petrol) this is as good but it is actually the worst of all, as it contains a lot of benzene, toluene and aniline, which are extremely "dry". Cars like your 420SEL use electronic injection and were designed to cope with lead free petrol, unlike the 1961 300SL I was driving today, which does need the extra oil, as it has a Bosch mechanical fuel pump - see pic below, taken when it was being serviced by Mechtronic in Germany.

dkCambridgeshire Posted September 30, 2013 Share #5577 Posted September 30, 2013 (edited) This thread is 'stuck' for want of the correct answer - but there are enough clues for anyone to give the correct answer. The car is not a Nissan Skyline GT-R ... they were totally different models and years ... so Toshack10's answer although 'warm' is incorrect. dunk Edited September 30, 2013 by dkpeterborough Link to post Share on other sites More sharing options...
