Looks like I found where all the oil has been coming from. I cleaned the engine as well as I could with a degreaser, ran it for 5 minutes at idle, and was able to spot a substantial leak coming out of the push rod tubes:
(IMG:http://www.914world.com/bbs2/uploads_offsite/i.imgur.com-23207-1560976029.1.jpg) I'm going to tackle this project this weekend. I've found some good older articles that mention it can be done without dropping the engine, but might have to replace the seals on a couple without fully removing them. I'm going to replace the valve cover gaskets, adjust the valves for the first time, and I'll being doing the first oil change since I've had it. I've heard Valvoline ZR1 20W-50 is a good oil to use, and I can find it locally. Thoughts? Aside from ensuring I don't damage the seals on reinstallation, and thoroughly cleaning everything, anything else I should keep in mind, or try to tackle while I'm in there? Any other tips and tricks are much appreciated. Thanks in advance for any feedback. |
