I really appreciate everyone who gave me their opinion.... very helpful. side note to lsmurphy, interesting that you post a link on your messages to a Christian Sabbath website, but include an ill-needed comment about the NPR sticker. Thought this forum was about Jeeps. Thanks to everyone else

This helps a lot and I appreciate it! (FYI - I wasn't planning on leaving the stickers on the truck!) Thank you!

I appreciate the input from all. I got some good emails and advice... thanks.

Oil in the air box

Good point. This truck is in the Charleston, South Carolina area

Hilarious

Sorry no pictures available at the moment, raining outside. What would be a fair price to ask for a 1990 Comanche Pioneer 4.0? 173k milage, A/C works Manual transmission, body in excellent shape (blue in color), bedliner intact, original Jeep radio (woo-hoo!) The Good - new transmission and clutch, brakes, alternator, starter, fuel pump, exhaust, hoses, lots of tread on the tires. Not so good - oil blow-by issue, lifters are knocking, no headliner or headliner panel, some small electrical issues (ie radio turns off and on, side marker lights not wired) Been driving it to work, hasn't left me stranded yet! Just don't care to put anymore time or money into it.

Yikes! Sounds out of my scope of skills. I got this truck for my nephew but he got something else. I have been piddling with it and driving it to work, will probably sell it. Thank you for your response!

Appreciate it!

What do I clean the CCV orrafice with?

1990 Comanche Pioneer 4.0. What is the typical cause of an oil soaked air filter? Also have oil collecting in that area of engine.

Wow, just got home and I am overwhelmed with the many responses. ALL of them are helpful and I am appreciative!! Thank you all :bowdown: I don't know what it is about this little truck, but I am bitten by the Comanche bug. It is like a puzzle to figure out the problems and see what makes it go. I have the money to buy another car if needed, but right now I am enjoying the simplicity of this ride. And as each of you know, there isn't a day that someone doesn't come up to me and tell me how cool they think these trucks are. Thank you for the links and the advice, I will get to work on the items suggested and happen to have a big ole bottle of Simple Green in my garage. It is so good to know there is a community of folks out there that are willing to share what they know and are patient with a newbie. I will remember to include pictures and more details with future postings. (and yes, there will be many future postings) Cheers all! P.S. to XxStirCrazedxX, actually I have flown a Piper Comanche in the past.... I never even made the connection! Good catch

Hey fellas, can use some tips and advise please!!! I picked up a 1990 Comanche Pioneer 4.0 a few months ago while moving and changing jobs. It was bought at an auction so I know absolutely nothing about the history of this vehicle. For all I know it sat in a yard or field or barn for the last several years. It runs decent and some of the basics had been already replaced ie. alternator, plugs, battery, hoses. I am a female with a background in airplanes. I have a decent amount of mechanical skills and have LOVED learning about this truck! I own a fair amount of tools and torque wrenches and such (inherited from 3 brothers that don't live near me). I had the brakes, exhaust and transmission replaced because they were safety issues and beyond my scope of time or experience to repair. Now I am working on the not so pressing items. There seem to be so many things that appear worn or questionable, but I can't replace them until I can identify what they are. Many of these things are relays and wiring harnesses, etc. I have been looking for sources and manuals to help me with this. These are some of my issues/questions and will gladly accept any other ideas and suggestions! Hint, electrical is NOT my strong system at this time. I am teaching myself and I am learning more about it with airplanes. I know many things can be diagnosed with a meter, I just haven't gained that skillset yet. 1) the truck runs OKAY, but not awesome. The lifters(?) are knocking away. How difficult is it to repair this issue? 2) it seems to take a few seconds too many to crank. In the past month there has been 3 occasions where it wouldn't start. After waiting, it eventually would start. I replaced the starter and the positive battery cable (which was worn). It cranks stronger, but still seems to take too long. I am looking next at the vacuum lines because they are cracked and old. After that I don't know which direction to go. There are so many relays and such that could be contributing to the problem and I don't want to randomly replace things hoping to hit the malfunctioning item. I want to make educated decisions. 3) How do I decide what to replace first? I have been trying to focus on one system, such as the fuel system. I have been replacing items in a line as I can identify them. For example I replaced the fuel pump, strainer, lock ring, fuel filter. But beyond that, I am not sure what relay goes to what and there are wires that are not connected to anything. I realize there are test ports and connections that are meant for items I don't have on this vehicle, so not everything is going to go to anything. 4) Would it be helpful for me to get a computer diagnostic test? 5) I think it would be helpful to clean the engine so I can better see what is worn and leaking. This lead me to wonder if there is a basic lubricant that is okay to spray on different mechanical parts of the truck (like WD-40, but better)? 6) Overall, there seems to be no end to the items that can be replaced or repaired. I just don't know where to start or how to be smart about the choices. I have been using RockAuto, NAPA, Advance Auto (and similar) stores and websites to shop for parts. Would love to hear what some of you gents have had good luck with. I have to run off to work so I will not be able to monitor this forum until I get home. But I will greatly appreciate any words of wisdom that can be shared. Appreciate your time guys and gals! 1wingnut
