My front oil cooler setup -- why's it failing?, Installed May 2007 Options

May this be a lesson to us all (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/headbang.gif)

Driving from Fair Oaks/Sacramento to Vacaville last Sunday. Filled the tank up before leaving town (1/2 tank of Premium gas). During freeway drive, started noticing and getting concerned by the rising oil temp and falling oil pressure. Peaked at 260+ oil temp and the 30 psi oil pressure reading on the gauges.

The engine made a sputter crackle sound like it was running rich at one point in slow traffic at the Hwy 50 & Hwy 80 merge. There was a puff of dark smoke upon acceleration. The engine didn't stop sputtering and there's been a knocking sound ever since, but there's no dark smoke. Lost my go power too. Feels like it isn't in the proper gear or something. Possibly missing a cylinder??

I stopped for lunch in Davis to let the engine cool off and stretch the dog. Drove some more without any noticeable improvement in the temp or power situation. Stopped at a 76 station in Vacaville to look more closely.

There is oil in the tank and it looks clean, but the level is above the fill dot.
No distributor wires are loose. Engine bay looks clean...No obvious oil leaks/spray. Got flatbed towed the rest of the way home by AAA.

Best I can tell, the oil may not be circulating properly. Best guess is that the thermostat isn't opening or there is a block in the oil cooler line somewhere but don't know why.

Leamon Stansell (HealToe914) did the oil cooler setup work in May 2007 (pictures below).

The car hadn't been driven much since. Half the tank of gas was 7 mos old (Premium) when I hit the freeway on Sunday.

Waiting for Rich Walton at Jerry Woods Enterprises to give me the go ahead to have the car towed to them for further diagnosis and repair but thought it *might* be worth getting *the group's* opinions/experiences on the subject.

I'm not a 6 porsche guy and don't think I ever will be. There is just not enough cheap parts around for me to ever consider it. But, I do know auto mechanics and the front oil cooler is probably more wrong than right. Get rid of the 90 degree fittings, go to better bigger lines, change the air exhaust path, it needs to be 30 to 40 % minimum bigger for exhaust than the front intake area opening, especially without a fan. Probably for what you want the factory 2.2 cooling is more than adequate. I also think maybe the cooler was added to try and fix a already existing problem and may have made it worse. I think the previous owner knew more than you give him credit for but you might have still gotten a decent deal. I will be happily surprised if this deal is done for 7k. Sorry about the whole deal but it can have a happy ending, you will end up knowing what you have and it should last a long time. I'm too hard headed to try to own hotrods and trust someone else to do the work. I think unless you have unlimited cash flow you should just get a factory newer low mileage hotrod. I know this is not a place to say this but the non mechanic, middle income guy or lady is going to really do without, to support a high mileage older 6 porsche unless it's driven a small amount and really monitored closely. You will lead a life of always needing a honest high end shop to do your repairs and maintenance. If your earned hourly rate is about three times the hourly shop rate plus the shops parts cost you might be able to keep up. Just in my opinion I think the porsche six is really neat and has a beautiful sound but not something that is cost efficient compared to new high performance stuff.
