Yes to the question of whether "Porsche" gaskets are Reinz gaskets.

The gaskets come in "Porsche" cardboard but clearly say Reinz on them

RED SHARK 1990

Ok, anyone on board who has had their engine refreshed-lets say with new head gaskets-,bearings,cylinder heads with a new valve jobs,and reseal the engine what would the least cost including removal and installation. Thanks,labor and parts.

Put another 50,000 miles on the car then decide what you want to do !

That is a loaded question, it really depends on how much needs to be replaced on the engine, but count on at least 15-18 grand to have a real pro 928 guy do it by the time it is all said and done.

James Bailey

Because most 928s are geared very tall the revolutions per mile are quite low and they are being loaded to a small % of their capability. So while 100,000 miles might be a lot of miles on a little high reving four cylinder it far far different for a 928. So unless you have high oil consumption there is no need to rebuild it any time soon.

I agree, the vast majority of engines get pulled because of time in service, not amount of service.
Time kills things made of rubber, lack of coolant changes kills head gaskets, not keeping a eye on crank preload kills thrust bearings, and not keeping up with T belts kills valves.

That's about as close as you can get, until it taken apart. I tell people 15K minimum. 20K is common.

Although the value of these cars has decreased, the price of the parts has not. It doesn't take a very big box of pieces to add up to 5K.

Nothing cheap when it comes to doing one right.
A rebuilt engine should be as good as or better than a new 928 engine, sadly many of the so called rebuilt ones are not.

They are out there, or will be soon, just more money.

Rob Edwards

For a more-or-less stock S4 complete teardown and rebuild, the way I would expect Luan to do it, I get about $7000 in parts alone. And this assumes that all moving parts coming out can go back in. Add a minimum of $7500 to pull, teardown, clean, send out for machine work, reassemble, and reinstall. And then start adding powdercoating, improvements, and slippery slope items. Lightweight lifters? $700. Colin's cams? $1600. A mildly modded 5 liter engine is a $20K exercise, easy peasy.

You know...every time .. I look at Mustang 5.0, Camaro, Corvette that have 30 years on them...they look cheap and they are not as mechanical sound as the 928's. Everytime I step inside my car, I am impressed with how well the interior has held up. The materials that they put into these cars are just not meant to go past the first 6 - 8 years.

I just did one on my car, cost for parts and machine shop work like complete head job and balancing the rotating assembly was around $10,000 , maybe more, I'm not counting hundreds of break cleaner cans and all the other little non Porsche stuff I had to buy like a few special tools like torque angle tool for the heads, $250 Dial torque wrench.....
Every wear item was replaced, new seals, cadmium coated every bracket, pulley, nut and bolt that came coated from factory, new head bolts, new cam gears, crank gear, rebuilt the original T-belt tensioner, new crank sensor, hall sensor, knock sensor, complete new spark plug wire kit (not just the wires). The only things I did not change was the MAF, MAF boot, and ISV.

I had to do the rebuild because I did not have an engine and the short block I bought had a #2 bearing failure, so it had to come apart.

Like everyone has already said, do it if you have oil burning problems or bad compression, otherwise I would not touch it.
If you just want to do the head gaskets, I wouldn't stop you, just make sure you buy new head bolts.

You have to also consider those cars cost a fraction of what a 928 cost when new. They are also much cheaper to repair and modify at least for the mustang and camaro.

Bill Ball

No plans for an engine rebuild anytime soon.

risaac928

Let you ask you guys this...not that I plan on rebuilding my engine anytime soon. But I was wondering as a back up plan..those rebuilds or used engines on 928 international...are they worth it...
