Which one were you referring to?? | | | | | Joined: May 2002 Posts: 155 Shop Shark | | Shop Shark Joined: May 2002 Posts: 155 | That's the oil fill tube with a screen in the can part to keep junk out of the crankcase..Also noted that valve cover uses 2 studs for hold down..Think you should e-mail the seller and find out what engine it is...possibly a GMC...

Its in the road draft tube location, and has the oil filler cap on top of it. | | | | | Joined: Feb 2006 Posts: 1,867 Shop Shark | | Shop Shark Joined: Feb 2006 Posts: 1,867 | That looks like a jimmy engine alright, and the tube is the crankcase ventilation tube (oil filler and road draft tube) with the oil bath filter element inside the little tub at the top. | | | | | Joined: Jul 2007 Posts: 461 Shop Shark | | Shop Shark Joined: Jul 2007 Posts: 461 | Its a GMC engine, alright, and I'll go with rustednuts on the road draft tube and filler. GMC engines originally had the size stamped on the serial number pad by the distributor- 228, 248, 270, 302, etc. I think the size is the first three numbers in the serial number on that pad- if the numbers haven't been ground off.

Also, it's kind of hard to see clearly from the crud, but you can make out GMC on the rocker.

Picture 1 from oldgmctrucks.com Picture 2 from oldgmctrucks.com UH OH, the links only work if you are registered at that forum. I'll try to find public links to replace them. OK, I scanned a pic from the maintenance manual and uploaded it to my site. GMC crankcase vent
