Default My 2cents

I agree with Hatchett's post and others...Job 1: Get an expert's opinion on the internal damage, then make decisions on a re-build, replacement, or.

The looming question is whether it has suffered a "catastrophic failure". If so, the costs of re-build soar to about $15K or more. If not, then a used engine can/will cost $5-9K, not counting shipping, installation, and "while we're in there stuff." These engines are very complex...only re-builds by an expert should be considered...amateurs need not apply.

All great advice, but it boils down to setting "your" budget first. Second, what's your total(car + rebuild) budget? If your numbers look good, then this should be a great learning experience and fun project to tackle.

I have no mechanical skills, never been on RL, never owned a Porsche but I paid cash for a non running 996 with no PPI.

Did we get that right?

Not trying to be negative but this is a good lesson for others, if this is legit, how not to buy a car.

Ouch. With every start more damage occurs. Don't start it again until it's fully rebuilt. You should also bore scope the cylinders to see the condition of the bore surfaces. Follow Jake's videos on YouTube.

Andy,

What are your goals for the car?

And your point is?

What's the point of scoping if the motor needs to be torn down and opened up?

You would be better off selling this car and buying a $25,000 nice 996, or an automatic 996 turbo. Money and time better spent.

like others said, drop the pan and have a look see, I'd also pull the plugs and scope them, then hand rotate the engine to see if it rotates ok

If it does, next thing I'd do is drop the tranny and pop the IMS cover off and take a look

Like the advice to drop the sump versus just examining the filter, this would help confirm the extent of the damage. If for some reason, unbeknownst to anyone at this time, the cylinders are NOT suffering from scoring, then that may give the OP some new found options to save money especially if he's rebuilding it himself.

Buying a $25K 996 that might have a looming catastrophic failure is money and time better spent.? Not to all of us!

right

ignore the fact that 90% of the 996s dont have cat failure

brilliant logic

so very tired of the fear mongering

And now, for something completely different.

I know of two engines that had IMSB failure, but were caught in time, and the engine oil circuit was flushed, the IMSB was replaced, and the engine ran. This is not an endorsement, nor is it a plan for one to follow, just that 'catastrophic' and marginal failure are two different things.

How much would it cost to replace only the IMSB? couple hundred.
How long will it last? From 2-200-2000 miles. Maybe

YMMV, objects in mirror, pro driver closed course, contents have settled, and may cause **** leakage.

I'm in Aurora and have some tools and manuals. Don't know how much help I could offer, but let me know what you need.

$7,500
^^Thats probably on the high end of what it’s actually worth. How much did you research before you bought it? Do you realize to rebuild the engine properly (even if you do it yourself) is going to run in the $15k range? If you do, and you’re up for it, more power to you! 👍
