"ANY 928 MOTOR IS A CRACKED BLOCK WAITING TO HAPPEN. THIS HAS ALWAYS BEEN THE BARRIER TO OWNERSHIP FOR ME" Those are the words of Chris Harris from GTPorsche Magazine Dec. 2007 edition, p.19

The author doesn't go into technical detail much, except to say "You can have the motor re-sleeved just the once, after that it'll be time to find a new donkey, and then have that resleeved. The way things are going, there may be very few 928s left running in the future."

As for my own experience, many of you know about my woes regarding Thrust Bearing Failure on the '90 S4 I bought; not discovering it until after I had sank $10K on various other issues (timing belt, tensioner, pulleys, wheels, etc.). Finally, she is where she needs to be at Greg Brown's shop getting a rebuilt engine put in. Anyway, Chris' article had me wondering if he was speaking about the common Thrust Bearing Failure issue or something else that I wasn't familiar with.

I understand that many of us get 200K + miles out of our engines before a rebuild is necessary, but this guy is speaking in terms way beyond a rebuild when he mentions re-sleeving. Although we are a devout group of 928 owners who dare not speak blasphemy, would there be anyone here who understands where he's coming from with this kind of speak? Is there any truth to it? If so, is he referring to the Thrust Bearing concerns that, thanks to Constantine, can now be prevented or something else?

One interesting footnote, I thought the timing of this article was deplorable as it is featured in the same issue celebrating the "928 at 30" (yrs. old that is) on the cover. Is it just me or do these Porsche magazine guys really dislike our kind; even in one titled "GTPorsche"? For crying out loud, the 928 represents that definition more than any other model in the Porsche lineup. Give us a break will ya?

as seems to be the favorite term as of late "search is your friend"

it is nothing but an opinion.......

there aren't that many block failures due to cylinder splitting that I've seen. block failure is sometimes (not always) caused by something else.

The last block failure (cylinder split) I am aware of was caused by a dropped valve. The valve head lodged into the cylinder head, the piston came up and hit it (numerous times) and the cylinder split at the top.......

If done right, a 928 block can be sleeved numerous times, although it should be a long time before you have to do it again----say 100,000 miles down the road????

Even Nascar engines are headed to "no top deck" configurations.

Thanks Russ

Ryan, I tried using the search engine, but using the words "cracked block" under titles yields 2 hits that doesn't answer the questions before me. I'm sure they're here somewhere, just a matter of finding the "key" words I suppose.

is there a production engine with more as fast race miles on it than the 928 Holbert S4? Plus being 21 years old!

If the 928 was being sold today, it would be a tremendous selling point.

What for a BS is that?

Mr. Harris, buy yourself a bike if you fear a cracked block. BTW it can happen to ANY car!

On the official list of things to worry about on a 928, "cracked block" is down around number 238, just after "strange oder from PO's 3 month old dead body".

Goddamn Ryan,

There is a guy from Estonia on a 924 board who said in 2005 that 928 hydrolocking and cracking the block is common, stupid guy says the block cracks easily because it is made of alloy (unlike the 924 of course )

I did not see any reader responses to this in the Feb issue. Somewhat surprizing.

Mrmerlin

Hey Schocki,

What type and color paint did you use on your engine? Looks cool!

Schocki

That's red textured finish done by Qualitypowdercoating in Dallas TX. I bought the intake tubes on Ebay first from Garrity. They are Mercedes Benz tubes. They are cut after the 3rd set of rings and a silicone tube is used for additional felxibility. I color matched the red silicone tubes to the textured finish. It is a nice red Ferrari like finish, it is way to orange in the picture.
