HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Leak testing an oil pan

Leak testing an oil pan

Post  Arthropraxis on Sun Dec 12, 2010 9:43 am

I was test fitting the crossmember and accessories while the motor was on the stand and noticed a couple drips of oil on the bottom of the oil pan. The motor is dry except for the residual oil that drains down out of the block. One of the drips is from the drain plug, probably not tight enough. The other is more of a worry it is at the front of the pan by a weld.
How could I test the welds integrity? Could it be filled with oil while on the stand and just sit to see if it leaks?

If you have an air compressor, that also has a adjustable regulator, set the regulator for say 15-20 psi and with a rubber tipped blow gun attachment, blow air into the dipstick tube. If you want, you can drain the oil and do it through the drain plug hole too. Thats the only method that comes to mind.

The motor is dry. The only oil in the pan should be what has drained down. I wiped the oil off an will look to see if any has seeped through. I will try the compressor and see what happens. I would be looking for air escaping in the area of the leak?

Yeah, you should hear some hissing at 20psi. Thats how I test my welds on my exhaust, although I use a solution of soapy water in a windex bottle to squirt on the welds to produce bubbles. You could use a candle around the weld and see if it starts dancing. Very Happy

Well, I didn't even have to leak test it. I was getting everything prepared to put the motor in for the first test fit and there was a leaking area right in the front corner of the pan.
I have no idea how to weld and sending it back to where I got it from is not an option. I do have friends that can weld. Is it possible or advisable to re weld that corner while the pan is still on the motor?
Any suggestions would be appreciated. I need to know what to tell whoever fixes it.

You can mig weld it while it is on the motor and it can be full of oil and still work fine. I've had the same problem before.

Tried to mig weld the pan with oil in the pan. The weld would just get cooled to quickly and was contaminated by the dripping oil. I took the pan off and had it welded and leak tested at a shop. It better not leak now, the repair cost more than I thought it should.

Check the crush/copper washer on the pan. The one that came w/ my RH pan is dripping ever so slightly Rolling Eyes

I'm guessing some thread sealant will help out the problem.

The drain plug held oil fine. The hole was in a weld where the modification was.
