Accusump install

I only check the gauge rarely, so the inconvenience is not a problem for me.

With plastic undercover off, the gauge is still hard to see because of the coolant pipes blocking the view I think I'll just install an electric pressure sender connected to a gauge in the cabin. Location TBD

I think the air pressure port is 1/16th NPT, put a VDO sender (same as oil) and wire it to your oil pressure gauge along with a switch to toggle the gauge between the accusump air side sender and oil pressure sender. I called vdo and they said it was ok, and canton will give you the thread for the air pressure port. I was going to do this but never installed my accusump since my fuel filter is in the tunnel and blocks it.

Steve! You are the man!
You always have the perfect solution!
I will do just that and I'll try to upload photos when I'm done.

Well gents, bad news. This is probably my issue.
Haven't looked at the filter yet.
The funny thing is the engine ran strong and still runs strong.
These particles are magnetic, so iron or steel.
Also there is a tiny little spring that I circled in red??? Variocam?

Any ideas as to what this is? Valve spring retainers? Looks like ribs on the particles.

The good news is it's early in the season:

If these particles are what they look like to me I don't know how this engine is still running! Yes, valve spring retainers and keepers plus that little spring (I think it's from a valve stem seal).
Take it apart before you touch the starter again.
Good luck!

I have to agree the small pieces with the ribs are valve keepers.

[AZ986S]

Looks like that is the case. The other pieces to me look like they are probably either the spring retainer itself or the the hydraulic lifter. Either way, there is probably a bent valve and possibly more damage, so the heads are going to come off I'm sure, and, if the engine is salvageable, I'm probably going to upgrade to racing springs, retainers and keepers.

Here's what the keeper (1/2) looks like:



There's a post on Rennline that discusses the possible cause for this happening. It seems like the bottom line is that Over Reving causes the valves to "float" and impact the piston, especially with high RPM operation such as DE or racing. These are made of sintered powder metallurgy, and are brittle. The spring tends to soften up with age and this adds to the problem.

I'll be talking to one of the Phoenix area Porsche racing specialists (Patrick Motorsports) tomorrow and see what they say

After debating all the options and talking to my Indy shop owner that did lots of work on my Boxster, my co-worker that is a dedicated and very knowledgeable Porsche aficionado, and shopping around (including looking at $25K 2010 987.2 Boxsters), and going through all the stages of loosing your baby, I pulled the trigger today and acquired a used 3.2 engine out of a 2000 Boxster S from a reputable Porsche salvage yard here in Phoenix. The owner also knows and works with my Indy so that is a plus for me. The engine is very clean, no oil leaks. It was owned by an older gentleman that backed up on a light post, and so the insurance company totaled it. Hard to believe from the damage, just barely any damage on the rear bumper. Engine apparently had some major work done at 38,000 miles and was pulled at 63,000 miles. No details on the work done, maybe IMS? That year I am told has the dual row IMS bearing (1% failure rate?), so my mechanic will pull the IMS flange, oil filter and inspect. I think I'll just leave it in there if there are no signs of wear or abuse. I'm also told that you can't re-use (pull) an LN Engineering IMS bearing after it has been installed. I had a ceramic dual row pro IMS bearing installed on my car about 7k miles ago. Might consider one of the other oil fed IMS bearing offering out there if needed.

It's tempting to just want to upgrade everything on the motor since it is out, and I will certainly swap a bunch of stuff I already had done on the motor to the used one.

I'm going to load the car on the car trailer tomorrow (after installing the winch) and deliver it along with the used motor to my mechanic. I will probably have it back by the end of next week and in time for the first PCA DE of the season No break in required!

As for the pulled motor, I might consider attempting a rebuild during this winter and keeping it as a spare. Or, might part it out.
Hey maybe I'll get lucky and I only will have to pull the heads.

Update on the used engine swap.

My indy called and told me that the engine I acquired was a factory reman with the unserviceable IMS bearing. I think that would make it a 987 3.2 2006-2008. Now I know what the "major engine work was"! I asked about adding a DOF system to the bearing, but he advised against since it might drop the oil pressure, so all he did was remove the outer bearing seal for better engine oil lubrication. Apparently engines from 2006-2008 with the 3rd IMS bearing design that is larger are supposed to be more reliable... less failures. True or not?

Also, I was not happy when my indy told me that the parts shop I purchased the engine from had cut off the Variocam solenoid pigtail and there was nothing to solder to... so they had to pull the valve cover from both engines, and swap out the old for the new. Looks like Porsche wants $500 for that solenoid! Other than that, I had them replace the AOS, plugs, tubes, water pump and also swap out from the old engine the IPD plenum, 74 mm TB, underdrive pulley and other stuff I had installed.

It should be ready to pick up this Friday and I'll get to use my new trailer
Can't wait to try it on the track at Wild Horse Pass:dance:

I will buy an engine stand and start diagnosing the old engine with leakdown first, oil filter examination, and then get into pulling the valve covers since debris looked like valve keepers. Maybe, just maybe I can save the bottom end.
