Porsche 1983 911SC Engine Clean and Inspect

We have been cleaning this engine since the last video! Many hours of cleaning have been performed, with more to go. We have a clean-up order based on some outside services. The fuel distributor and warm-up regulator have to get out early, as well as inspection on the crank if it needs work. The heads stay here, so they have not been fully serviced yet!

Building up to rebuilding my first engine, which will be an air cooled 911. Really appreciate these videos.

Your welcome Kurt

Hi Kurt, Do you actually remove the cam spray bars, and do you seal them back into the housings when you do? I had planned to remove mine to clean them really well, but Henry from Supertec mentioned that they come sealed from the factory and breaking that seal when you remove them will reduce the oil pressure, I don’t recall if overall or just to the top end.

[@klassikats]

I completely remove them. Once the plugs are out the pipes just slide out. There is no sealing compound in there and no it will not reduce oil pressure to remove them. You do have to make sure that the pipes are orientated correctly when re-installing so the the spray jets are pointing at the right place. When I re-install the cam plugs I do put a very small amount of 574 loctite on the plugs just to make sure everything seals up with no leaks.

Thank you, Kurt - great videos and amazed at your knowledge which I am sure is built up over many years! I have a 1986 3.2 that I am rebuilding and wonder if removing the oil galley plugs is similar? also If you don't have the tools to make the crank case plugs - where would you source these?

[@klassikats]

Yes the case is going to be the same. Some of the plugs you can purchase from NAPA or Autozone in the form of a Brass freeze plug. However, the other aluminum plugs are not available and will need to be fabricated. This is not a hard job for someone that has access to a lathe and accurate measuring equipment. Kurt

Great video Kurt...love the tips...i can tell you have a loving wife..God bless you my friend...😇

Thanks so much Kurt

Good Job Where do you send your k-jet components?

What medium do you use to blast the casing parts ? Do you seal it with anything after blasting?

[@klassikats]

use a mixture of Glass Beads and Aluminum oxide. After blasting I use a ceramic tumbler to close the pores which acts as a type of sealer. If we are looking for a bright effect sometimes we will use clear Cerrakote on the part. I do this on all carburetors to seal and protect them. Kurt

👍2-15-00 engraved on the fuel distributor 2:24 does that mean anything?

[@klassikats]

Not to me... people put all kinds of things on parts. It may mean the last time it was serviced or maybe installed, who knows??

[@ianhands9289]

Thank you for making these videos, I'm just disassembling my 78sc engine, and this information is a god send. Are there any parts that I should not get vapour blasted? Thanks

[@klassikats]

I would not vapor blast items like the crankshaft, or the cylinders otherwise most items are okay to be blasted. Kurt

Approximately how much was invested in all the parts needed for this rebuild?

[@klassikats]

an engine job like this will cost between 18K - 25K for everything. Kurt

[@peterfrode2378]

Great video. Really like your content. I have a 3.0 SC engine too that I need to rebuild. Looks like you are planning to reuse the cylinders and pistons. What are the parts that you would absolutely recommend to change on those engines? (Mine is a US model)

[@peterfrode2378]

Also would really like the series to continue on this built

[@klassikats]

so re-using parts is based on condition and every engine is different. Cost is also a concern as everyones budget is different. Yes we are re-using the piston and cylinders on this engine as they are still in great shape and will still offer a long service life. When looking at a part I ask myself will it go another another 100,000 miles? if not I will most likely replace it. Kurt.

[@peterfrode2378]

@@klassikats That makes sense. What would you say are the best upgrades while you are so deep in an engine. I see a lot of folks put Mahle (3.0 to 3.2l) cylinder and pistons in and different valve springs etc. ?

[@klassikats]

I would have to say that most "Upgrades" that I see done are poorly thought through and often result in more issues than good. Changes in displacement, cams, springs, etc. need to be thought out and the appropriate changes to fuel, spark advance, and exhaust made. Kurt

[@RLtW88]

How many miles/kms we’re on this engine?

[@klassikats]

No idea? The owner said the odometer states around 65,000 but the engine says otherwise. Kurt

[@RLtW88]

@@klassikats the infamous TMU! I’m about to pick up a ROW 83 myself, but thankfully the mileage is all accounted for.

[@harrypatterson8802]

Please rebuild my 82 911 sc 3.0

[@klassikats]

Sure you can reach us at [e-mail] and we can talk about when you would like to do the job. Kurt
