An odd skip

[Shag Wagon]

Ok here is my situation. Me and some people cant figure it out so here it goes.

Ok most of the people on here know of my 93 CB7 I just got a couple months ago. When I bought it it was skipping really bad. I gave it a tune up and newer plug wires and it runs WAAAY better than normal. Now I have this stumbling when I crank it up in the morning and it skips oh so very lightly. My passengers dont detect it but I know its there. I also noticed that my coolant tank over flowed after a 30 minute drive across town on the interstate. It has never done this and I have taken it to the boonies of North Carolina and back which was a 6 hour round trip. I also need a valve adjustment. I have a very audible tapping occuring and will be something that I will take care of as soon as I can. But anyways what can be the leading cause of this? I know I need lower tube seals but I dont think that is causing it. Anybody have any ideas or things I need to try before I conclude that I have a blown head gasket? EGR ports have never been cleaned.

check cooling system, see if it holds pressure and check your cap.

Ok I am going to replace the cap as soon as I can.

Here are my compression test results:

121-121-120-115.

I think my compression should be good. I might have a bad or clogged injector somewhere. Might just need a fuel filter. But there is an ass load of oil in the tubes. That might be the cause of my skipping and I am going to have those replaced asap.

I had that stumbling a year ago...it was my headgasket that was leaking. My compression was I think 90 on all 4. I had honda do a block leakdown test and that revealed cyl 2&3 had coolant going in there.

The stumbling got worse and worse as time progressed. It never died on me though. I drove on it for about 4 months like that, so it was a slow leak.

Aww mang dont tell me things like that.

Anybody else with ideas?

oil on the plug wires will do it, get a valve cover gasket set and replace the tube seals.... get a new set of wires and go from there. a new fuel filter is never a bad idea, but i don't think thats your probelm.

Well its got a new valve cover gasket and the guy I bought it from said something about tube seals. I guess they already did a leakdown test and got it fixed. I guess ill go ahead and get those upper and lower tube seals ordered and put them in on the next nice weekend I get. Might as well do it to my wagon too.
