Engine Drp and Minor Refresh

[49willard]

I have dropped the engine and trans for the first time on my 86 911 (the last Porsche engine drop was my 356 over 50 years ago!). I have a 2 post lift and modified a cart to R & R the engine and trans. I built in capability to tilt the engine back for R & R. All went well. I degreased and power washed the engine, trans and engine bay, a challenge mid January in Maine!
The primary reason for the engine drop was for fuel and vacuum line refresh and a potential clutch. It turns out that the clutch is due! Someone before me must have ridden the clutch since my 911 just has 65K original miles. I plan to reseal the triangle of death. I am doing new 1/2 shaft boots and reseal the transaxle.
There are lots of things that I could do "while I am in there" (example Heidi and Frannie refresh on their 86 cab) but I plan to keep it simple. It is a totally original 911 and plan to keep it so.
Your thoughts?

Great time to adjust the valves and check for broken head studs. Replace intake gaskets and any hoses?

[49willard]

Thanks for your response. Yes, I will do a valve adjust and check the studs. I had done an exhaust valve adjust and checked the lower studs about a year ago. All was well on the bottom end then. I plan to do all engine bay hoses except AC. I could do intake gaskets I guess. I am very focused on doing those items that are much more easily done with the engine out.

Good time to smoke test the intake looking for leaks

Transmission ground strap- new one and clean the mounts on the body and transmission for good contact.

Clean the starter wires and contacts as well.

Great time to check/replace the vacuum line for the brake booster. Also check both halves of the injector harness for green guck on the pins/sockets.
CH temp sensor and flywheel sensors?
The vacuum venturi assembly and associated hose clamp/adapter madness and the hoses behind the intake. I removed my intake and “while there” pulled the air shroud/alternator and cleaned a bunch of acorns out. The alternator had worn slip rings. There was a bunch of oily crud from the leaking triangle.
Oil cooler o-rings.
Good luck staying warm!

Thanks for your thoughts, keep them coming.
I have been ordering parts but cannot find a part # or locate the smallest diameter (looks like 10mm x 17.5 mm) of the three hoses bundled together on the backside of the engine (as viewed from the rear of the car). It attaches to the engine air filter housing and the oil tank. I assume that its function is to evacuate oil fumes from the top of the oil tank. See smallest diameter line in the pic below.

Need help posting a picture. The website asks for a URL. No URL for my personal pix.

You need to Go Advanced, not Post quick reply.
Then you will have access to the feature called Attach a Photo. You can then click on it and drag and drop or browse for the picture on your local computer and upload it.

Trying it myself with this pic.

Wazzz,
Thanks for the help!
The hose I am trying to find is the smallest diameter of the 3 hoses in the pic below. All I could find was a listing/part number for a length of hose off a coil, not a formed hose like the original. I have ordered the 2 larger diameter hoses in the pic.

Looks like it is part 28 on page 48 drawing of this pdf.

This is Porsche part number 930 207 236 00.

You need to take a goofy picture of yourself standing in the engine bay, look mom I did it.

Don't forget to swap over the brass restrictor that is inside one of those breather hoses. It allows the engine to still idle, when the oil cap is removed. Quite a few people forget this and throw it out and wonder why the engine wont run.

Also, the vacuum hose that joins from the rear of the intake boot to the brake booster assembly; check the rubber for cracks... it's common for it to fatigue allowing air into the system.

Thought that this was mandatory; buried in Forum Rules somewhere.

[49willard]

Thanks for the part #. It appears to be no longer available. In all fairness the subject hose does look fully serviceable. I will have to decide to stay the course or make up a hose out of off the roll hose. If anyone knows where someone has a new formed one available please let me know. I sent my 2 fuel hoses off to Len Cummings today for a rebuild.

I think the Heidi and Frannie refresh on their 86 cab is a great start... look at the #8 bearing nose seal (or something like that) if its leaking. If it is not leaking, maybe its best to leave alone... tough call though.

[49willard]

As I stated in an earlier post.I am looking to do a more minor refresh than done by Heidi and Frannie. They did a full cosmetic in the engine bay. I am doing a more functional refresh. Their 86 cab had almost twice the miles that I have on my 86 Cab, same color exterior and interior it turns out. My cab has not leaked oil anywhere and does not consume any oil between oil changes. I will reseal the triangle of death however since it is so much more accessible on the engine stand. I am glad that I decided to go after the fuel lines. The crimp of the flexible feed to the hard tee can be twisted/turned at the crimp, I could have had a fire in the future.

[49willard]

Making good progress on my refresh.
Can anyone tell me where this bracket on the yellow sticky goes, I can't find it in any pictures but I do remember taking it off?






I indicated earlier that I would salute the guy that R & R'd the original fuel lines with the engine installed. Having just installed the engine compartment sound insulator pad, I would also salute the guy that installed it with the engine installed.

Where are the axles ?

[proporsche]

the bracket goes on middle bottom -under the nut(no alu washer with it) and it holds the no 6 cable..but you need the plastic clip.... not important to have, many do no longer have it..

Axles are out awaiting new Porsche boots. I am waiting on several parts including refreshed fuel lines from Len. I can then finalize and reinstall the engine.
