Hi guys!
Eventually - a year after my car chew on an air cleaner stud - I'm getting round to rebuilding the engine. It is a real pity about that stud, as
all the measurements are within a couple of hundredths of a mm with no real sign of wear ... this engine could have lasted the rest of my life!
Anycase, I have some pickings for your collective brain. Some daft questions, possibly covered elsewehere (if so please point me to the url), but
here it goes:
- How important is the emision control valve that sits on top of the oil separator - my engine has the seperator but not ECV. If this is critical,
where can I find one? Or should I just pipe from the seperator to the rocker cover and from there to a catch tank?
- The Haynes book of lies (or was it the Wallage book?) recommends replacing all major fasteners, e.g. main bearing bolts, big end bolts and head
bolts. I understand this is best practice, but what do most guys do in the real world?
- The steel crank pulley mentioned in the books, is that the timing chain sprocket?
- What is your experience r.e. ligtening and balancing. Worth it on a fast road spec engine (40DCOE's, free flow 4 into 1 exhaust, racy old-skool
cam ("one up from GT spec" and 40thou oversize 1300 pistons) to be used as Sunday run-about and for the occasional track day?
- The steel crank pulley recommended in the books - would that be required on an engine with the above specs?
Many thanks!
Francois

........or you could keep yours for spares & bag yourself this beauty

Postage from Bristol may be a small snag though!!

@ David ... thanks for the useful advice .. will post again as and when I hit a brickwall or the proverbial hits the fan.
@ Blackie ... yeah postage to South Africa would be a major problem. As a matter of interest, for that sort of money we can buy 4AGE blacktops in
reasonable nick imported from Japan ... makes 160-odd hp straight from the box, no trick parts required. I love the Kent crossflow motor for all the
nostalgic reasons, but my next 7 will be built around the cloned and upgraded Japanese Ford BDA engine ...
Right, found a decent place that do a lot of work for local works racing teams to do the balancing ... only problem is they don't do lightening. We have a fully equipped machine shop at work, so I'm thinking of gettin the conrods and flywheel lightened here before sending in for balancing. Only problem is ... where do you take the "meat" off and how much?
Found this excellent article a while ago about lightening flywheels.
