Since We're Doing Gratuitous Engine Rebuild Pictures

[jluetjen]

Since there seems to be a surge in engine rebuild pictures, here's a couple of mine of my race engine. Unfortunately I've been stalled for a few weeks (with my piston pins in the freezer as my wife keeps reminding me) due to other obligations like day job and family holiday prep. I hope to get back to it soon. So far I've done the deck height, and just need to install the rest of the pistons and cylinders before moving on to the top end.

John,

Looks good! I see you used plenty of Tectyl on the mag case. I think this is a good idea particularly given the tendency of magnesium to corrode.

When I do my race engine I'm going to have Ollies tumble the case and then treat the whole thing with Dow 7, also known as Iridite, or another conversion coating such as Alodine. It turns the case brown but it's a good corrosion preventive for mag.

Did you run into any snags doing the deck height or was it pretty straightforward?

I see you have the hexagonal plugs for the oil pressure and relief pistons.

Daughters car.

Who would have guessed that?

Hey, OT, we need to do another Porsche wedding event! Who needs wedding singers when you've got Porsche owners/drivers as part of the procession?

I know where some matching seats can be found.

The bypass mod was done by Competition Engineering, and they provided the plugs. As far as the deck-height goes, I've been putting cylinders on and off again more then I intended. I've come to the following conclusion...

1) Standard ring compressors will get the pistons into the cylinders (see my work bench in the back), but the pistons will come out again while you're futzing around with the piston pins.

2) Much better to get the Porsche ring compressor that looks like an oil filter wrench. Put the pin into the piston when the piston is out of the cylinder and then use the Porsche piston compressor to install the cylinder over the piston. Then un-hook the compressor's strap and take the ring compressor off from around the piston.

In my case the deck-height came in pretty much nuts-on to what I wanted.

Gud plan on the ring compressor. I hung 3 pistons on rods and got after them with my new from Pelican KD ring compressor......the SOB wouldn't fit around/between the studs & piston. Great....
Off they came and back to the old method on installing the pistons in the cyls and ripping hide off ones hands working between the full thread studs installing pins & clips........auggh!

John,

That's the ring compressor I already have, it's actually a HAZET 794.



They are kind of expensive, around $150, but can occasionally be had on the used market for less. It's an old tool, was originally used on VW engines, and has the advantage that you can slip it off once the cylinder is on.

Glad to hear that's a better solution, my pistons and cylinders are next to go on.

That's the one that I've got John. I bought it and a bunch of other "Porsche Engine Rebuilt Tools" off of ebay. Well worth the investment!
