My Cheap Porsche 911 was Hiding a Huge Problem (dealer wants over $20,000 to fix)

1. I’ve got a M97 engine with 59,000kms. Bore scoring is inherent in all these engines simply due to gravity as the pistons run sideways along a flat six cylinder. Where Porsche failed is to align the cylinders with appropriate liner. So you having bore scoring is no surprise. Should you rebuild the engine with the appropriate liner now or later is owners call. Since the bore scoring has started, it’s a ticking timebomb to watch carefully which you’ve done. It might not happen for tens thousands miles but it will require a rebuild. And if you sell the car it should be disclosed and will greatly affect the sale price. In the meantime you can enjoy the ride you and I share.

2. You have a large field and farm animals, not hard to resolve the wife issue.

3. You should do your leak-down tests near the bottom, not tdc. This way you will find any possible cracks in the bore.

4. Sam, I would recommend using Teflon oil additive to the oil changes…
   Or Marvel mystery oil.

5. Can valve covers be resealed on a 2000 911 cerrara without dropping engine?

6. Give your stepmom a present Sam………..a new cock. 😆🐓

7. Not crazy i would try the liquid head gasket too

8. Your cock chasing you around brings back childhood trauma! We had a Rooster with long leg spikes, and that Sum'bich would chase me around all the time trying to feed the hens. One day, as I ran screaming like a little girl, he jump up and got me in the back with them spikes! I was only like 7 or 8 years old. lol. I think we had chicken the next night for dinner….don't remember. HA!

9. You buy these exotics Porsche and Ferrari but can't afford to fix them properly. All they are is time bombs for you with huge bills that don't run right. Fix them properly or sell them unless you like looking at them or bragging you have a Ferrari.

10. Head gasket sealer won't work I have tried it on a Cummins 5.9. Even the $50 one from Walmart that's guaranteed.

    This is a Porsche not some junk Korean import definitely won't work in the flat 6. It's a performance car. Fix it properly if you can't afford to dump it.

11. might not be some fancy Wheeler Dealer mechanic, but I respect how you attack problems and are interested in learning.

12. Like the Detroit tee, go Leafs

13. Use 1 quart sodium silicate to seal the block. Adding sealer to the radiator only works permanently with cars were the leak is into the cylinders. Sodium silicate has a trick. This is the best way to use it. remove the exhaust just before the catalytic converters. Flush the radiator clean. remove the thermostat for the process then replace it. Fill the system 3/4 full of clean water. Run till 180 degrees, turn off car, add the sodium silicate to the radiator and crank, add the more water till full while running and cap when full. Run car for for 30 minutes at operating temp. Turn car off and remove spark plugs. The sealant will work its way into the cracks. You will waste your time if you do not pull the exhaust loose and remove the spark plugs after running for 30 minutes. I perfected this method and I can seal any crack or gasket leak with 1 quart of sodium silicate, if the exhaust gasses to not enter the oil. Anyway, let car cool. Reinstall Spark plugs and crank car. before removing the sodium silicate, recheck the bore for moisture. If still moist, which is not likely, run till hot for 30 minutes while hot then shut off, remove spark plugs and let cool again. If there is still moisture in the system, My name is mud! Reinstall cat converter, flush radiator, being carful not to splash the sodium silicate anywhere, it will damage any surface it touches, so remove it carefully. add antifreeze, spark plugs and you are all set!

14. YES ON HEAD SELANT i have used successfuly for 50 years, also.liquid steel

15. Expired dealer tag.

16. If your bore scoring is not causing excessive oil loss, I wouldn't worry too much either. No engine will ever be completely perfect. I own a Porsche Cayman 987, so I do understand the OCD involved in wanting your car perfect, but ripping the engine apart for no reason seems dumb.

17. I'd drive the heck out of that Porsche Sam.

18. Yes, dump some kind of motor medic in it.

19. I thought those f&ckers were air cooled. Shows how dumb I am.

20. Why don’t you just pull the engine line the cylinders and replace the head gasket check the IMS bearing and store that thing away 997 ‘s are going up in value quickly 👍 will cost around $2k and a bit time
    I can guarantee that head is not cracked it’s the gasket gap between the cylinder and water way is very small , the head may corrode beyond repair if you don’t attend to it quickly , the hot water blowing past will eat aluminium

21. Did Brewster finally end up on the dinner table?

22. This 2007 car will have the larger IMS bearing designed by Porsche to sort out the previous problems in earlier cars.
    The reality is that this bigger bearing is totally reliable (as far as any mechanical component can be), so you've got absolutely no problems there.

23. If this was a powerblock show, they would pull the engine, hone the cylinders, square the heads and replace the head gasket. On a Porsche, probably 9 million dollars so nevermind.

24. You said let you know what we would do… "Renegade Hybrids" LS Swap. 😎😜

25. I’ve got a 996 with bore scoring. Been driving it for about 30k now still runs like a top. My Porsche mechanic told my to drive till it dies. He said I can replace the motor now or later doesn’t matter. I think it’s kinda waste of a perfectly good engine till it dies. I’ll replace the engine when the time come.

26. I’d run it with the sealant as long as you can. You have a good idea of the cost to repair/replace the engine and the cost of sealant was less than 1% of the repair! You could do an update video every 5,000 miles – I’m sure most of us would love to know how the sealant works out and who knows, if it works well, you may end up with a new sponsor!

27. Stick in the goop!

28. Your "My proverbial rooster in my hand" comment had me rolling dude!!🤣💯

29. 🤣

30. Personally, I'd throw a bottle of something into it first. It might not be sexy but, while I've lifted chassis off of engines with an engine hoist, you really need a lift to do it right. Since you're getting a lift, a cheap head gasket sealer for now and a teardown later is probably your best bet.

31. Out of interest is the bore scoring found on the lower section of the piston? Always wondered if flat engines suffer with more piston wear on the bottom side of the pistons due to gravity.

32. Can you request different annealing process to the crankshaft like they used to do it in the old days because bore scouring seems to emanate from laser annealing instead of the true and tried method for a fee ofcourse

33. boohoohoo 6 dollars a Gallon.. here it is 2.50EURO per Litre..
    A gallon is 4.5Litres, a Euro is a little over a Dollar atm I think… so here in Europe we pay like 12.50Dollar per Gallon. Now stop whining.

34. Try block sealer.

35. I really like these Porsche 911 videos. I am looking to buy one here in the next year or so. Probably a 2000-2008ish 993.

36. honestly i´d Hone it , repair the headgasket and send it

37. just found your great channel an subscribed keep up the good work !!

38. whuy not try it.

39. Hey sam, thinking about the bore scoring, have you heard or thought about adding Tungsten Disulphide to the oil. I used 50g/2oz at an oil change in a 3.0 tdi audi a5 quattro and it made a big improvement. Check it out online as its too detailed to go into here. May help with the scoring and give a small compression boost. Cheers, frankie

40. Order a new improved short block from Porsche $15,000 with $4,000 core. Rebuild both heads by specialist $3,000 to $4,000. Do the assembly work yourself. You'll then have a decent car! Personal experience. These engines are time bombs. Buyer beware. Nice video.

41. "Most simple sports car ever made, Porsche 911"
    * Miata and S2000 making a crying Michael Jordan face *

42. LS SWAP IT!!!

43. Good video, but doesn’t cost that much to fix a head gasket. Tops 5 grand

44. If the engine scares you call Renegade Hybrids and get a LS kit and have some American iron in there.

45. Paint the car a different color and you should be fine

46. That intro was hilarious 🤣 🤣 🤣
