3.2 Carerra: Engine rebuild after blown high presure oil line

Oil line blew during touring at HSR.

Engine shut off too late.

I inspected the car and it's systems the day before, and service had been completed over the Christmas holidays, therefore it all was so unexpected that it is hard to believe.

Step One: SPEC by Machine Shop of the engine is required:

I expect to need a crankshaft (rod bearing failure) to begin with tand two oil coolers. Considering stainless steel braided oil; lines. Cylinders and valve train components should be good, but would like to have guides looked at. Engine on a pallet.

I.a. Ordering a book from Performance Products and Wayne's too. Ordering PP tool kit.

I.b. Compiling a list of parts to take to machine shop:

Anybody have a list? How about the best (P & Q) source for crank shaft? How about the braided lines and connections, oil coolers, oil lines.

Car is daily driver and PCA.

First Porsche Engine rebuild.

Bernard,
I would relax and see what the machine shop says.
I don't know how much time you have. Wayne's book is very good and I would consider it a must read before doing anything. You can get a lot of help on the forum. I'm rebuilding my 3.2 top end and had what seems like a 1000 questions....things are getting better now. Let's wait and see what others say on this forum.

I'm getting help from other PCA members and I have a good Porsche repair place helping me also.

In any case good luck.

Sorry to hear about your misfortune. Exactly what oil line blew? Was it a factory line or aftermarket?
I've seen aftermarket braided lines inside the right rear fender get rubbed through and make a mess.
I've sent oil coolers to Pacific Oil Cooler for cleaning with good results. I don't know of anyplace else that can do a proper job.
(I'll be sending them another cooler tomorror actually.)

Wayne's book has a great table on page 69 that shows machine shop labor costs. You can use it to decide what, besides the obvious damage requires, machining you'll need.

Rebuilding a 911 engine is difficult, but far less so with Waynes book splayed open on your workbench. Good luck!

Engine sent to machine shop. JB Racing, and Mike Bruns in Taveres Florida did the machine shop work.

Block tolerances all with Porsche factory specification. Crankshaft has scratch from spun bearing, but didn't really get hot as it didn't discolor too much, and may be refurbished easily by qualified Porsche crankshaft specialist. Armond at CCR can get it back in spec. He comes highly recommended as only one who does Porsche cranks for many of us here in Florida. P & C (alusils) good. All other engine parts except crank where in spec. Camshaft and rockers all within specification. The heads were disassembled and cleaned by Mike and all checked out in spec.

Spare motor (with new topend rebuild) in the car. Car runs as good as before. Very strong! Haven't broken her in yet so can't say much else other than a friend of a fried saw me during the initial break in drive... oops too much fun.

Front oil coolers went to Pacific Oil cooler and came back refurbished. Engine oil cooler from spare motor sent too. Discarded original engine oil cooler as did not want any debris in fresh motor.

Removed and cleaned hard oil lines and thermostat (brought it back from black to fresh.

Amazon Hose and rubber helped build all new rubber, and rubber metal hoses. Good to know all my oil lines and breather hoses and all hoses are new.

I recommend everyone refurbish their oil lines, as Mine looked fine prior to blowing. I spent $2.1k in labor at Vertex (and they missed it... they had engine out and I had them repair any problems they found (hmmm careful guys. Go over other people's work yourself[$1.9k in parts]) in Miami immediately prior to the oil line giving out (engine oil line [under engine to thermostat]between rubber and metal)

Everything is detailed. Looks new again (pics soon). Even the control arms were deatailed and look like new. Shocks, axles, just about everything shines like new under there. Transmission cleaned too. Needs a little more and it will be nearly as clean as the motor.

I pulled the motor myself, (and put in freshly [top end] rebuilt) 3.2 motor I bought from Rick's European in Largo Florida) disassembled it, hired machine shop, R & R oil system including tank. Installed spare motor. Car runs strong!

See you at Brumos race next week in Daytona. Nope just a spectator .

Oh did I tell you while I was there, I R&R'd AC system with new hoses and valves and pressure teseted condensors and evaporator. Spent $8.2k.

Have one guy interested in trading her for a race car, Huh? too much fun.

I had Mike at JB Racing rebuild the top end of my spare motor('84 3.2). All new intake valves and exhaust guides. Mike put together the long block, I put the sheet metal, alternator, engine shroud, intake, harness, clutch(new [Sachs with spring centered disc] last time car was serviced)etc together. Installed the motor by my self. Yes I have been called son of Hercules (OMG that would be a joke in another language). But seriously, I did it and it is possible.

Now I have my original motor ('87 3.2) that is back from the machine shop to rebuild and get to do it all myself. No hurry have to do lots of planning Should be fun building a monster 3.2!
