Rob your library of pics never ceases to amaze me.

Thanks Brian for posting this. Just ordered my test kit from Blackstone I've been wanting to set a base-line and then compare it each year.

this is a great pic......then the center mounted, spring loaded rubber center section that literally "sucks" into place...you have to push the pan in place just a little bit to get the spring to compress

also you will need to change to the early dipstick......otherwise you are forced to rip a hole in the mesh screen.....this is how I ran the estate....but the early pan goes through the little hole at the bottom on the pic

What are does black plates behind the screen, do they just lay there, I did not know they had that behind the screen.

How do you split a block in two? Isn't that almost like breaking an anvil?
I understand if you don't want to talk about it but how can that happen?

Mark Anderson

I seriously do not know what happened other than many hours of stress that it was never designed for. The split ran right down the middle and had the block not failed that motor may still be alive. Everything was worn but still usable.
This was not my latest motor but the one previous. My latest motor is still in the car so no idea what went wrong there.

Thanks for sharing. Like I said earlier I was sorry to hear of the failure.

Ali-

Here are two shots of the 'petals' that surround the early pickup, and serve as baffles:

Wow, do the petals get sucked up by the pickup tube once the car is started? I guess that is what Brian means by center section getting sucked into place. Interesting design....
Thanks Rob for the pics.

No- it's solidly bolted to the bottom of the pan

all my engines are runnng today, and have NO spacer breather systems, scrapers, accusump, dry sump, nothing. and I RUN FLAT out!! dod you remember what anderson needed to run a 140.1 at laguna?? 420rwhp on DOTs. !!!!!!! data point, im running 372rwhp and running 1:36s. NOT to say anyones better or worse as a driver, but to say, when you drive the car hard, you drive the car hard. if i have made the car last by doing so, DO WHAT I DO and you will be fine! that goes for not only laguna, but sears, thunderhill, road america, etc!! reinvent the wheel and take your chances. there are rear view cameras on my car showing no breather issues. i have oil analysis to prove the engine is fine, i even have 10 year old engines with 100+ races on them to see what has actually worn!!!!
giive me all the theory you want, but test things emperically! i race and race the 928 motor hard with NO oil pressure issues run a good engine (brian, dont toss in your suspect engines that failed to the mix they were "dead men walking engines") run amsoil, the right weight, and dont carve turns at redline, and be smart on the track and you will have no issues with the 928 engine. PLUS, go through a good warm up routine before beating on the engine. get it heat soaked before pounding on it on the track. (oil temps to 180 at least)

Everyone knows how much you believe in the stock S4 oiling system, but the harsh reality is you are the ONLY one that can make it survive on track..... Sean had properly rebuilt engines blow in 10 hours on track.....along with all of the other engines that I blew up or found damaged rod bearings in....

6 Engines total.... driven on the same tracks as you with MUCH more time on engines.... You count "races" or "race days" I count HOURS ON TRACK..... The estate is nearly 100hours.....my current engine is around 8 hours.... A typical race day for you is maybe 45 minutes on track...only 25 at race pace... Less if you just do qual and race....that could be a 35 minute day..... Scott's hasn't see a race in years.....

I try to get at least 2 hours on track PER DAY.....otherwise why go....

Don't forget all the issues 944's have on the same tracks..... This is something that we will NEVER agree on, and I tried it "your" way and have the trails of engine parts to prove it....so did Sean, so did Louie ott, Don Hansen, Dennis Kao and others that all blew engines (or came close) at Thunderhill....

Honestly the only way to truely test your theory is to data log your oil pressure vs G forces in turns with both you driving and others.....but we both know the minute someone else drives your 928 what will happen..................."boom" comes to mind.....
