Got 2 days off this weekend but spent those entertaining the girlfriends mother. Actually had a great trip out on the steam train complete with fish and chips in the sunshine. Lush 8)
Did a shorter day at work today (a rarity) and the 'rents had invited us over for dinner, complete with Mama's home made coleslaw that just can't be beat - would be rude not to go!
My mate Tintop had dropped off my new carbs earlier in the day, picked up from Stanford Hall, so with a new found hour or two found in the working day we set about giving the old engine a once over.
My father and I rebuilt the engine for the old bus which must have been... maybe even 2 years ago now :shock: But since it has been sat, untested and unloved in a garage we were very pleased to see it turned over by hand!
...about 270 degrees... :msn4:
So a slow teardown ensued. We wanted to do everything to avoid splitting the case. Actually, that's a bit of a lie - I was saying "bugger it, let's just crack her open" and my dad persuaded me against.
I won't bore you with the details but we eventually found the cause of the problem: the new cam, an Engle, was fouling the oil pump!
As soon as I popped the oil pump off it turned freely by hand with little effort :mrgreen:
I remember having to replace the oil pump when we built it up, partly because I cracked the old one when removing it and partly because I knew the aftermarket cam needed a different pump.
I forget where I bought it but suffice to say, despite being armed with the knowledge that I needed a pump with greater clearances, the one I fitted didn't seem to give me that.
This is where I was up to when I was called for dinner:
Not sure what to do about the pump.
Current thought is to attack the rear very carefully with a grinder to get the necessary clearance. Loathed to do it because the pump is basically brand new, but it is better than shelving out another wedge on that engine.
Anyone after an oil pump? I didn't scrimp when building that engine so know it is a good one (albeit incorrect for my set up :msn4: )
No idea when I'll next get to play with that engine because I am likely to be working next weekend as well (another lovely 12 day stint). Itching to get the bugger built up and swapped in though!
