Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I cleaned my engine using simple green and a brush, then I put 303 on the plastic, last time I took the engine cover off it still looked pretty good.

Suggestion
Often the joint between the first section (in the trunk) and that one will fail, causing it to leak when you change the oil.

Hello Nix, what have worked well for me is to first use a couple of cans of engine degreaser from the auto parts store, rinse (** w/Very LOW water pressure, then clean it again using Simply Green (to remove the oily residue of the engine degreaser)..

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hey Gang, I am 3 weeks into ownership of a 2001 986 Base "Heidi" 51K miles and giving her some TLC and really want to go after the engine and clean it up. What do you all recommend on how to do this properly with the right cleansers? Attached are some pics of the engine compartment but also noticed oil build up on the manifold hose. There are no oil leaks but the oil filler hose has some build up (see pics). Is this normal for a 20 year old car that has never had the engine cleaned? TIA!

POST 3Original post

I would suggest taping off the engine area with plastic sheeting so you can use a hose (at low pressure as Gilles mentioned) without worry about getting it inside the car. I also covered any exposed electronics with plastic and tape, they should be waterproof, but why risk it. I cleaned my engine using simple green and a brush, then I put 303 on the plastic, last time I took the engine cover off it still looked pretty good.

POST 4Original post

The tube in you second photo is the oil fill tube. It's a 3 piece assembly, you're looking there at the middle section. Often the joint between the first section (in the trunk) and that one will fail, causing it to leak when you change the oil. I would clean the engine and pay attention to what happens at next oil change. If it leaks again, time for a replacement. Sent from my SM-G970U1 using Tapatalk
