KMAPRO Posted November 2, 2009 Share Posted November 2, 2009 OK, I had a posting on here somewhere talking about an engine swap, but I could not locate it with just a quick look around... This is my 87 Comanche. I am having to put a quart of oil in it about every other day. I think I know where the bulk of the oil is coming from, but I don;t really know how to fix it. Here are a few pictures so that maybe y'all can help me out: Most of the leak seems to be coming from the top driver's side of the engine - right around the vacuum thingamajiggy (sorry, I am not a mechanic, but I am learning): A close up view of the area: Directly below the area: I also think I need to replace the rear main seals, but they are not the biggest source of the oil leak: Accumulation of oil deposit on the frame rail next to the vacuum area: Now, I do know that the engine has a bad ring on the number 2 piston and I am having to run an anti-foul adapter so that I don't foul the plugs every 100 miles or so. The vacuum attachment is right above this cylinder as well. Is this why I am getting so much oil presence in this area? Any and all help would be greatly appreciated.

maddzz1 Posted November 2, 2009 Share Posted November 2, 2009 looks like you have some serious blow by. Pete has a pic on here where he uses a catch can to catch the oil. Mjeff87 solved his problem by switching to a newer style valve cover. Is your air filter full of oil? here's one link: viewtopic.php?f=2&t=12871&hilit=valve+cover Link to comment Share on other sites More sharing options...
KMAPRO Posted November 2, 2009 Author Share Posted November 2, 2009 I know I am going to get bashed for this, but I don't have an air filter in there right now. It was that way when I got it a couple of months ago and I just haven't spent the dineros to get one yet. BUT - I do get quite a bit of build up in the bottom of the air box. My best guess is that the air filter getting gummed up would explain why there wasn't one in there to start with. I plan on going to the local pull-a-part this weekend. Hopefully, I will be able to grab a VC and all that I need so that I can try to get this oil leak stopped. And YES, I will also grab an air filter while I am out.... Thanks for the link and I will let you know how it goes. Link to comment Share on other sites More sharing options...
deziped Posted November 2, 2009 Share Posted November 2, 2009 NAPA got rings. Link to comment Share on other sites More sharing options...
Pete M Posted November 2, 2009 Share Posted November 2, 2009 mine was so bad that i ran a vacuum hose from the valve cover to a jug, and then a line from the jug on to the air filter. It caught the oil pretty well. Link to comment Share on other sites More sharing options...
sinkrun Posted November 2, 2009 Share Posted November 2, 2009 Mine leaked like that i used a newer (96 up I think) valve cover they have a full baffle in them. The one in yours now has 2 towers very poor design. I did have to re route some vac lines. There is a post on here some where on how to do it I will try to find it. When you buy one of these and there is no filter its a sure sign was blowing into your air filter it will clog them fast. Link to comment Share on other sites More sharing options...
KMAPRO Posted November 2, 2009 Author Share Posted November 2, 2009 So, I am assuming that when I go get the valve cover gasket, I should get one based on the newer valve cover as opposed to the original 87 model? I know NAPA has rings, but I don't have the time for the tear down, machining and rebuild. I am having to use this truck while my other truck is down with a blown engine. Just like my Daddy used to say, "Everything I've got - I either have to fix it or fill it up".... Link to comment Share on other sites More sharing options...
maddzz1 Posted November 2, 2009 Share Posted November 2, 2009 Yes, get the newer valve cover, and use the newer style valve cover gasket with it. Get the felpro gasket, its worth the money. The newer style is black and has little washer looking pieces with it. The older style is blue. Link to comment Share on other sites More sharing options...
88mjmanche Posted November 2, 2009 Share Posted November 2, 2009 yup mine did that and cloged the air filter and stalled my motor it wasent getting any air . just take the valve cover off ( very easy ) and take some break clean and a wire brush and scrape all the crap off the inside. o yea and when you put the cover back on locktite the bolts. inline 6s are known for having the valve cover bolts come loose... but don't over titen :thumbsup: Link to comment Share on other sites More sharing options...

Pete M Posted November 2, 2009 Share Posted November 2, 2009 side of the road ingenuity at that. :D I had a smaller catch bottle in place, but when I finally had the truck out on the freeway for hours on end (heading to Moab), the little bottle quickly filled and the blowby air pressure spewed oil all over the place.

Pete M Posted November 2, 2009 Share Posted November 2, 2009 yeah. too bad there aren't oil leaks in the typical rust locations. :( Link to comment Share on other sites More sharing options...
dakal Posted November 3, 2009 Share Posted November 3, 2009 pete. kudoos for driving to moab with the engine like that. :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :bowdown: :brows: Link to comment Share on other sites More sharing options...
Pete M Posted November 3, 2009 Share Posted November 3, 2009 More than once I was told I was crazy. :D After 3k miles I almost made it all the way back. Got within 2 hours of home when the water pump bearings gave out. Link to comment Share on other sites More sharing options...
Oizarod115 Posted November 3, 2009 Share Posted November 3, 2009 the blowby can hopefully be fixed with a valve cover and some cleaning but it is possible that the engine is WTFO (wore out ;) ) bad piston rings can cause this problem also by pushing compression into the oil and spewing it out the vent.

Pete M Posted November 3, 2009 Share Posted November 3, 2009 someone once told me that a worn timing chain can cause blowby too. Link to comment Share on other sites More sharing options...

Yeah, as mentioned, I do have a bad ring on the number 2 piston. I am just hoping that this can be a quick inexpensive fix that will allow me to get by until I can get the engine in my Dodge replaced - then I can yank this engine out and do a total rebuild on it.
