OK guys - my 1982-era Green Cloverleaf engine has 1400 miles on the clock and was installed in the Green Machine last year. The engine was still crated from AR when I bought it, although for some reason in the intervening 20 years one of the inlet valves developed a crack and was replaced with parts raided from my 1978 Ti engine.
I don't want to ruin what is essentially a brand-new engine, so I would like to know what the best plan for routine servicing should be, such as...
1 - what oil to use? My Haynes manual says 10/50 or 10/40 mineral oil and I have been using 10/40 to date. I have heard a lot of talk about synthetic oils - are they really better for a 'Sud engine?
2 - cambelt replacement? I put new cambelts in last year, but I need to replace the camshaft oilseal on the LH bank anyway. Should the belts be changed every 12 months? I'm only asking because the procedure for replacement in Green Machine is even more entertaining than a normal 'Sud, involving mirrors and lots of cursing...
3 - still haven't got to the bottom of my carburation problem yet (been off sick for a couple of weeks), but how well do twin 36 IDF's stay in tune? Should I be investing in a synchronometer?
4 - my transaxle is easily the weakest link in the whole drivetrain. It is a 1978 Ti unit and 1st and 2nd synchromesh is very poor. I am nursing it by blipping the throttle on essential downchanges. I changed the oil completely about 500 miles ago. How long can I expect the 'box to last? Should I be thinking about getting a re-build/replacement?
5 - I still have the intended engine for Green Machine in pieces in the garage - it's a racing unit (never been assembled) from Warrior Racing and is allegedly a 1600cc (1.7 crank in a 1500 block) with Cosworth pistons, gas-flowed heads and stainless valves. I have seen a local company called A H Motorsports who deal in racing Boxer engines - does anyone know if these guys could build up my Warrior engine for fast road use?
Lots of questions I know, but I am looking to clock some more serious mileage this year and I don't want any mishaps in the engine department!
Thanks for your help,
