Black Pig Too

   After drawing the cam and releasing the torque converter we lifted the motor out and turned it over. The crank weights show impact marks from fairly large bits of debris as do the undersides of the pistons. I was pretty savage about it all by now and loosened the rod journals and knocked the pistons and rod assemblies out expecting the worst. Apart from some light scuff marks on the skirts they seem OK, even the bearings were reasonable, but will be changed, where's that list. Last out were the mains caps and crank, all remarkably clean considering what has been going on in there.

   So, now it's fully stripped and we can start cleaning and really closely looking at stuff, it's certainly not as bad as it could have been, but not pretty. Minimum required will be cam, lifters, retainers, bearings for cam, rod and crank, gaskets, oil and filter. It is time to sit back and have a bit of a think about all of this and decide if we just replace like for like or step up a level, cost will determine it. There is also the issue of what happened first and why, heads will be scratched, chins stroked knowingly, perhaps a bit of nodding, and then we will nail it all back together again and see what breaks next

Ooooooohhhh, bugger.
That's gonna be the most expensive engine never to run down the strip Steve.

No that one's still across the pond

Can't remember -have you told the boys & girls about that one? I'm losing track of your stable of race cars. How many you got now? Is the Yankee motor destined for the Moggy Minor bodied Altered?

"Come on, keep up at the back "

 Thanks matey.

Just had a management meeting in the pub, to discuss our options.

After a quick look he found the problem

   hmmm, not ours but just about the same cost to put right ! So far we are looking at Cam, Cam bearings, oil gallery plugs, lifters (possibly rollers), pushrods, guide plates, springs, caps and retainers, main bearings, rod journals, oil pump, timing chain set ( or maybe gears !) head gaskets, possible head skim, more oil and another bloody filter ! It looks like two concurrent problems, one part masking the other. The cam problem, I think, started with a little valve/piston contact, this in turn possibly promoted by weakened springs ? this wasn't spotted at the time as we were chasing a misfire and strange fueling issues. These were squarely down to the new copper head gaskets not sealing, letting oil into the bores and blowing through the centre two pots on both sides. The gaskets are good and work well on other combinations, just not ours, apparently, still, they'll polish up nice and look good on the wall. So, piss poor diagnostics (that'll be me) and failing to make the decision to fully strip it earlier (er, that's me too ) another leason maybe learned. We are currently awaiting quotes before deciding which way to go with this mess.

That's some tough mice you had in that engine Brock!

 "We are currently awaiting quotes before deciding which way to go with this mess."

What he actualy means is he's waiting for quotes before he tells me how much more the b****y thing is going to cost me

And the out come is,an order to real steel for new cam bearings,oil pump,head gasket,big ends and a new catalogue (F.O.C if you spend over £*** with them).

Several phone calls to our contact over the pond and lots of deliberating on how much we actualy need to spend as opposed to how much we want to spend, if any one can remember as far back as the start of this project, it was supposed to be a cheap and quick project to get us out on the track last year while we waited for the new engine to arrive for the new altered. (After 27 years with Brock you'd think I would know by now his idea of it won't take long isn't what the rest of us would term as not taking long),the outcome was we would have a shiny new cam and valve spring set to be shipped within a week.

Now bearing in mind how long we've been waiting for the other engine to arrive, when Brock said the Cam would be with us a week Monday (15th), I became very despondant thinking well that's it there's no chance we'll be at the track Easter weekend, so I had quite a shock yesterday morning when the door bell rang and low and behold there was the little man from fedex stood on my doorstep with new cam in hand.
Excellent service as it was still in San Clemente on 11th, 4 days door to door.

Now if only Brock can get him to deliver the engine  


Oh and all things being equal Avonpark here we come

[brock]

   yep, big box from Mr. Fedex containing all we asked for. New cam, lifters, springs, inner springs, inter springs, titanium caps and locks, valve seals, lubes and gaskets, all packed in local newspapers, anyone want to buy a four bed, three bath house in gated comunity with own pool, $285,000 available immediately due to mortgage default, I'll look at the shiney bits instead.

[brock]

  Cam looks nice, very clean and sharp, and so it should be. Lifters are solid with extra oiling hole in base. Titanium caps really are noticably lighter than steel ones. Springs go boing. A switch in gasket from copper to the steel shim took static compression from 11.4:1 to 12.6:1 simply by reducing thickness and having a tighter bore clearance, shouldn't take long to bugger that little lot up.

[brock]

   Tonight we dialed in true TDC on number one, lubed the cam up, fitted it in and set the gears and spent an hour or so checking the specs on the card against the actual installation, all pretty close, as in parts of a degree out, I'm willing to write that off as being due to having a mil thick pointer on the wheel, should maybe have ground a point on it. Still, so far so good.

dont copper gaskets usually have piano wire too?
