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.

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

POST 1 / ORIGINAL POSTEROriginal post

Saw this today and thought I'd ask what might be leaking. Looking from rear of car, left side of car. Car is '99 C2. Thanks in advance.

POST 2Original post

I'm thinking its a spark plug tube. I had the same leak same spot with a drip on the header. It's common.

POST 3Original post

You probably need to change plugs, tubes and seals. There are good referances on how to do this but don't be fooled into thinking that this is an easy DIY. Pretty complicated but very doable if you remove the mufflers. It will give you chance to check your coils as well.

POST 4Original post

Hmm, this is interesting. I've got a similar leak on my left bank. Mine doesn't drip on the header/exhaust manifold though. I just assumed that the valve cover is leaking (it's not a big leak, a few drops per day maybe). It's actually leaking a little bit more now, as I've had the front jacked up on stands for a few weeks in the garage now. It may be time to jack the back up a nd pull the mufflers off to check the spark plug tubes...

POST 5 / ORIGINAL POSTEROriginal post

OK, thanks guys, I'll keep driving until next service

POST 6 / ORIGINAL POSTEROriginal post

Dealer advised it is the left side valve cover that is leaking and quoted $1,522. Will be taking to indy on Monday for 2nd opinion.

POST 7 / ORIGINAL POSTEROriginal post

Update: Sneaky Pete and Hurdigurdiman were right. Indy changed out all spark plugs and tubes, cylinder head plugs and the cover piece with seal for the camshaft adjuster solenoid. While there I had him install the LN spin-on adapter, oil filter and magnetic drain plug. He drove it around, kept it overnight to check for leaks and released to me earlier. Cost was half of what dealer quoted with incorrect diagnosis. Nice!

POST 8Original post

I had the same leak on my boxster, mine appeared to be a cam cover. It was very minor and I had just let it be. It was irritating smelling it though as it dripped on the header. It was on the left side on my car too.

POST 9Original post

"Dealer advised it is the left side valve cover that is leaking and quoted $1,522. Will be taking to indy on Monday for 2nd opinion." Hence the term "Stealerships"... scumbags! What were they going to do, replace the valve cover because it was leaking? Jezzzz...

POST 10Original post

Leaking cam covers is a common 996 issue. I had one bank resealed on my '99 as part of the "nail everything down" service I had done after purchasing my '99. Of course, I was paying indie pricing, not dealer pricing. I considered ignoring it, but having oil all over one side of the engine makes it hard to spot other issues if they crop up, and stuff just gets caked with dirt. That repair is 99.9% labor and a few bucks for the sealant, so if you're paying dealer service rates, it's a pricey job. The dealerships definitely like to pump the well for as long as they can. I make a decent living, but I don't think I'd keep the 996 without a good indie and decent mechanic skills of my own...the car doesn't need a ton of work, but I can't imagine paying dealership book rates for routine maintenance.
