I did search... Really... Partial engine drop Qs

[500_19B]

I thought a search would pull up lots of info on this, but apparently not.

I keep hearing "partial engine drop" and it sounds sort of obvious. However, can someone more precisely define what constitutes a partial drop? I am intending to put in a new engine sound pad and a partial drop seems to be suggested for a good job.

Thanks!

amjf,
I assume you are speaking about your 911. You can do a partial engine drop to replace your engine sound pad. The term is relative to how far you want to drop the engine to get the work done. Here are some examples:

1. To reach over the engine and R&R the throttle cable, oil pressure switch wires, etc. - you would support the engine with a floor jack, loosen the clamps on the air duct hoses, remove the two rear engine mount nuts, and lower the engine 2-3 inches (measured at the rear mounts).

2. To R&R the starter motor - you would disconnect the battery, fuel fittings, oil breather hoses, and power steering hose leading to the reservoir then support the engine and remove the two rear engine mount nuts and lower the engine about 6 inches.

3. To remove the intake manifold, and everything connected to it - you would disconnect all the above and also the CV joints, clutch cable or hose, and the transmission shift rod before loosening the transmission mounts about an inch. You might have to disconnect the oil lines (drain the oil first), heater duct hoses, and the electrical connections in addition to all of the above in order to drop the engine as far as the jack will allow.

4. Any more than that and you will have to raise the car. At this point you might as well do a full engine drop. It's not that bad, you just have to have control of the transmission end and check everything twice. I think you will find it is much easier to replace the engine sound pad if the engine is out of your way. Of course, this gives you the opportunity to clean the engine bay, replace that cracked heater duct hose, check that pesky oil leak, replace the oil pressure sender, check your clutch with a visual inspection, touch-up your engine tin with some nice semi-gloss black paint, etc. etc., etc.,...

Good Luck,
Mark

Hi Mark,

Thank you very much for that response, that is exactly the information I was hoping to learn. I have removed the motor from my 944, which was a vaguely similar operation in that I dropped it out the bottom, but what I really wondered is what sort of in-between stages of engine loweing were possible and your post really summed it up well. Thanks!
