Ed Hall Posted May 18, 2005 Report Share Posted May 18, 2005 Someone probably over tightened one of the oil lines and it ended up cracking the oil filter mount that I have pictured below. I ended up buying another oil filter mount at the junkyard but the old one has an extra port. I’m confused on what size of tap I need. I already drilled and tapped with a size 12 - 1.5 tap but it was too small for the oil pressure sensor to screw down. Is a ½" pipe thread tap the right size tap? I do know that a ½" MIP fitting from Home Depot screws down the hole of the cracked oil filter mount perfectly. Is this tap on ebay the one I need? Click Here to View Tap!!!

Scotty Posted May 18, 2005 Report Share Posted May 18, 2005 Personally I would get the correct oil filter adaptor..if I could, if you want me to try to help I have be truckload of junkyards on Long Island, Mike Give me the specifics 1988 eldo, what engine? I love going to the junk yard, I need to thank them for Matt's engine anyway... Let me know Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life. Link to comment Share on other sites More sharing options...
KHE Posted May 18, 2005 Report Share Posted May 18, 2005 I think the lines have a straight fitting rather than a tapered pipe fitting. The ebay tap looks like a NPT tap (tapered). I would find the correct oil filter adapter. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...

It is probably very rare since very few of these cars were made and it looks like they took a standard adapter and hand tapped it to get this extra port. The only engine I haven't checked that might have this extra port is the 4.9 block. Link to comment Share on other sites More sharing options...
KHE Posted May 18, 2005 Report Share Posted May 18, 2005 Ed, Do the oil lines have fittings that are like the A/C fittings? A washer face that is swaged on the tube (near the end) with a hex fitting on one side and an o-ring on the other? If so, those fittings are straight fittings, not tapered.

Yes, the oil lines are as you described but the port that I'm talking about is for an oil sensor that has tapered threads but fits into a hole that looks not tapered. Probably what I need is a 14 - 1.5 tap but I'm not sure. Link to comment Share on other sites More sharing options...
Scotty Posted May 18, 2005 Report Share Posted May 18, 2005 Is that the second outlet? This is from a 4.9 manual Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life. Link to comment Share on other sites More sharing options...
Scotty Posted May 18, 2005 Report Share Posted May 18, 2005 Here it is with the oil cooler lines in the pic on the 4.9 Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home.

Ed Hall Posted May 18, 2005 Author Report Share Posted May 18, 2005 I marked on the picture where the port is located. Link to comment Share on other sites More sharing options...
Scotty Posted May 18, 2005 Report Share Posted May 18, 2005 Sounds like you can drill it! Interesting....

Ed Hall Posted May 18, 2005 Author Report Share Posted May 18, 2005 I already drilled it out but don't have the right size of tap. I'm pretty sure it's a 1/4" NPT tap that I need since a 1/4" MIP fitting from Home Depot screwed right in . I tried calling a number of machine shops around but could not find anyone that wants to do it. With the right size of tap, it would only take about 2 minutes to do the job.
