How do you do a compression/leakdown on 930/965?

How do you do a compression & leakdown on a 911/930 since the spark plug is on the top side of the engine?

On a 964/993, it's easy to do it using the bottom plugs.

But on a 911/930, is it possible to use the flexible hose that normally come with the testers to screw into the sparkplugs hole?

thanks,
anthony

I found it to be a PITA, but it was the first one for me. Using the flex hose seems the only way to do it.

I did a leakdown while I had the engine removed from the car. Thats one way around the space issue .

I did a compression test on my 930 using the flexible hose screwed into the sparkplug holes.
Had to remove intercooler, air filter and also the rubber elbow between CIS and downpipe. Removed fuel relays while testing

What relay are they and where are they located?

I am attempting to do a compression and leakdown on a 965. I've done compression & leakdown on a 964 before, but never on a 965.

Any other things I need to look at while PPI'ng a 965?

thanks,
anthony

Fuel relays located up front. Should be two red ones side by side.
