I took my 911SC in for a valve adjustment. I had no experience with this mechanic, but he is close to my home and always has Porsches, Ferraris, old MB, etc. in for service (must know what he is doing?). What threw me off was his insistence that the engine be dropped to "properly" adjust the intake valves. I cancelled the service.

Is it necessary to drop my engine to access the intake side? Any experieces on would be appreciated.

Hi Todd,
I have an '82 SC, and I've never had anyone drop the engine to do a valve adjustment.

It's time to find another mechanic.

 

Run away... run away...

 

Thanks for the replies! The shop, upon closer inspection, is more a high-end used car dealer. The owner, who dealt with me personally, probably feeds this BS to every Porsche, Ferrari, Bentley, and Mercedes owner he talks with. He also told me to sell the car immediately -- based solely on the mileage! It's too bad -- I was hoping to take one of the Ferraris as a loaner!!!!!

This is not unusaul practice for a p-car mechanic. There are 2 reputable shops within an hour of my house that do a partial engine drop to adjust the valves. Both have been in buisness for over 20 years, and look after some pretty impressive p-cars ( A 934, 993tt Pikes peak winner, cup cars, etc.).

My advice to you is get the Bentley manual & 101 projects for your 911,and learn how to do this yourself. Or find another p-car ownere (nut) in your PCA area, and have them give you a hand. The $ saved can be used for other improvements or repairs, and over time can add up to quit a bit of $.

Huh?! I am a p-car mechanic and in 18 years I have not once dropped the motor out of any form of 911 only to adjust the valves. It's a three hour job on an SC. No more.

Find yourself a new shop. Good Luck.

 

How far is a partial engine drop? I have read about them but the only partial drop that I have done was just far enough to change motor mounts. That said, it seems like with a partial engine drop, the intake valves would be less accessible unless the engine were dropped 18 inches or more.
