It never actually blew up..... I just broke it !!

You see, little things that go wrong, can sometimes grow into nasty things.

A little thing like a gauze pick up on the oil pump falling off inside the sump, with no indication that anything has happened.

Everything is fine, until something that the gauze should've stopped, gets up into the engine.

Then hit a patch of water on slicks whilst acellerating hard in second, and the engine spins to 8,000 r.p.m. in about half a second, but long enough to break a bit off a valve spring.

Then the little bit of valve spring can't wait to get down to the sump, where the nice "open" end of the pick up takes it up into the pump impeller , and instantly jams it.

Then the oil pump drive, stopped at the bottom, but still turning at the top, becomes something that looks like a "drill bit", and breaks.

Not satisfied with that, it decides to locate itself between the crank, and the conrod, bringing EVERYTHING to an instant stop, which then breaks a timing chain etc. etc. et....bloody c.

I now have a few devices installed that will hopefully stop this sort of thing from happening.


The engine rebuilt ...( again )
this time also has........
New oil pump with sturdy pick up ( checked and checked again )
Rev Limiter installed at 7,000 r.p.m.
Shift light at 6,250 r.p.m.
Extra gauze patches glued over various holes in the valley to keep any "bits" from going south if we break anything.


Fingers crossed !!!!

See how it all goes in a few weeks I guess.

Warren.
