I've rechecked tdc AGAIN. tdc mark at top at case seam. Rotor arm pointing at no.1 lead on cap and at no.1 cylinder. Vac can facing engine hatch. Check valves on no.1. The left valve is correct at 0.2 mm. The right valve is tighter at o.15mm. So I rotate engine till tdc back at top. Rotor arm now pointing at no.4. Check valves, both at o.o5. So this is definitely not tdc. The first one is correct yes?? Rotate engine round again to tdc. Which means at tdc the right valve has tightened up for some reason???? The valves were definitely correct previously, set 0.2mm as per instructions from engine builder. The leads are on cap in correct order. 1, 4, 3, 2 in clockwise order. Can I safekly adjust the valve and try starting again? Or the valve having tightened up somehow, is something badfly wrong somewhere that needs sorting?
I'm running again, idling well and I'm at least in the right ball park for getting it tuned up. BUT The oil leak I previously mentioned , has not got any worse /leaked anymore while the vans been sitting , although a drip was still visible on the case. But It is quite bad while the engine is running, a large drip of oil falls off every few seconds, enough to create a nice puddle under the engine. It's not going to get any better is it?? Can see the drip infact it looks like 2 drops on rear of case, middle of pic
Glad that the engine is going again, and you're moving forward (now she's running, you've gotta keep her for the summer hey? ) Your oil leak picture and description of 'nothing hardly when sitting, but continual drip when the engine is going' sounds very much the same as mine. Apart from your oil being a lot cleaner looking! Must be a TES engine thing But well done on getting it going!!
How much oil does yours loose then? I'm a bit alarmed by how much is dripping out. There just happened by chance to be a plank of wood sitting right under the drip catching it, and it was a right old puddle. Was running for maybe 10 mins or so. At that rate I'll be using more than my old engine on a mway trip
Yeah I wanted to check with all you experts first in case it might be caused by something obvious I can look at. I'd assumed it'd be leak free , I know everyone jokes about them leaking but really there's no reason why they should is there. Don't think I'd be happy driving it like that and I'm sure it'll get worse, unless anyone can tell me different?? Worst case scenario (or best case depending how you see it) is he says he swap me another unit. It's taken me 4 months to get this built and in.......
In fairness, I've not put anything under it to measure as such, and my driveway is so old and cruddy that it just blends in. I top up occasionally but never that much - a little oil seems to go a long way in drip form. Definitely it drips regularly when the engine is idling, and gets sprayed around all the bars and bits I don't know the names of when I'm driving - but nothing much to speak of when it's just sitting on the drive with the engine off. My engine is a rebuild from 2009 (although very few miles in that time) but yours is a new rebuild... it shouldn't be leaking just yet surely? Send 'em an email, it can't be 'expected' to happen straight after a rebuild just because the casing is 40+ years old.
Its probably case join or oil pump in that location, or someone forgot the large washer on the crankshaft that fires the oil back in, ring them Monday see what they say.
Shouldnt be drippy at the back like that. Ok, this is likely the oil pump cover not on properly or the paper gasket not sealing right. Take the rear tinware off, start the engine and see where it is running out from. The oil pump is something that can be sorted out or checked without taking the engine out. Even changing an oil pump doesnt need engine out. I just checked - GSF have the pumps and covers. I have two used ones in my collection, and a brand new CB Maxi 3 pump (full flow external hoses to filter / cooler type)
I seem to remember someone having an issue before and they said take the van there and they will sort it !!
Lets hope the engine wasn't built in the Outer Hebrides. Its all this Marmite that I hate about these buses
No - i`ll tolerate most things but have a friendly word , far better than going in with all guns blazing but up to you ... Looks like the oil pump seal so could be an easy fix ?? Good luck and well done
Ah no I'm not angry at the bloke, I accept sometimes these things happens, and if it's not an easy fix for me , I'm far more likely to get sorted out by him by being polite, that's not an issue. I'm just angry for myself (such a self centered ) cos it's taken so long to get here , so near yet so far etc blah blah. The thought of pulling the engine, strippinv it, building another, etc makes me want to blow my brains out.
