This Week… Its an Oil Leak…
So I changed the rocker cover last week, reused the gasket thinking it would be OK. Swapped them over, torqued the bolts back in and away we go… Wasnt very long before the smell of oil was periodically passing through the car on trips. Quick look in the bay when checking oil levels, there was an obvious leak back left of the cover. Shouldnt have reused the gasket. Doh! Clive at Autotronix was sound enough to order me in a gasket, picked up a CAS (cam angle sensor) Seal as recommended to change at the same time, £1.50 and a 5 minute job whilst the rockers off.
Glad I picked up a CAS seal (from David Manner’s Group J2 M5 Birmingham, real helpful guys), on closer inspection it had also been leaking fairly bad. If you havent changed one before, its not really difficult.. Its a good idea to mark up the CAS before removing it, that way the marks can be re-aligned and timing is unaffected. Unplug a few plugs, undo the 12mm bolt on the back of the rocker, slot the CAS off, switch the seal, (I had an awesome picky tool and a spare set of hands to pass me the new seal) line it up with little adjustments, a little firmer to push in with the new seal, push it on into place and line up your timing marks. Job done. I couldnt get it out from behind the head but there’s enough room to maneuver a simple O ring change, so it doesnt need to come fully out of the bay.
There’s been a bit of a blow on the stock exhaust system, so whilst I was down at Reddicap Performance Garage today, Philip put it up on the ramps and had a look. One of the Cat gaskets had disintegrated so he let me loose with the sealant.. Oh dear…
So that was another little fix off the list and half a tube of sealant gone. Lol. Whilst it was in the air, I took some brake cleaner to the leaked oil spots (had made its way down the back of the engine, round the sump and gearbox) and cleaned it all off. Its in the air frequent enough to notice any more oil leaks under there, be easier to spot on a clean slate.
Anyway, all work and no play is no fun at all. So quick once over with the fairy liquid and off to a local gathering. No burning oil smell, no blowing zaust, just smiles per miles roof down 🙂
Till next week…
