Thought It would be helpful for all--- This is a cut & paste e-mail just sent to 3Tech just starting to get the gameplan going. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 3Tech, I'm glad I'm smart enough to do the research before just picking up the phone and dialing. I really respect your schedule and how precious time can be. With that being said, here's the scoop. 94 1.0L suspected head gasket. Easily removed the head and now I am contemplating what to change- if anything at all. All my studies at the forums seem to indicate an advanced gear and having a delta cam. I am definitely interested in ordering the headbolts at best. The research I have done has really only made me think, re-think, then over think some more. I am taking the head tomorrow to a local shop (southern California) to have it inspected. Barring no bad news, I may just be able to get away with doing the gasket & not really worrying about valves & guides and rebuilds. I would love to do it all, but investing in the headbolts allows me to rip it back off again should the bottom-end really have a problem. Sorry for the rant. It basically boils down to this- In your opinion, will the cam & gear be a worthless investment along with only replacing the headgasket- OR does the cam & gear setup mandate having to rebuild the head??? I have a strong feeling that- The existing head gasket I just exposed had been replaced shortly before my acquisition of the car. It does not have the proper oil holes coupled with a shoddy radiator and poor cooling ultimately broke er' down (not to mention it was the ONE and ONLY time my wife had the car???.) I am going to dump some money into all the little stuff ie. seals, belts, tires, pcv, lines, radiator, gonna do some suspension stuff etc got a pretty good list going. To extensively re-build or not...... Thanks, Chuck ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- To all that read this, let's remember that there is such a thing as incredibly busy people who are incredibly busy because they are busy helping people. Seems there has been some inpolite threads on 3tech's "service." Thats my 2 cents. I have lots more questions in reguards to the repair/rebuild, and will let the thread take hold. Happen to be a bit busy myself. Got a date with 2 little blonde girls to greet the arrivals & watch the work continue for this weekends Long Beach Grand Prix. It's more fascinating than the actual race- just a 5min bike ride down the path on the beach!!!

Chuck, If you were happy with the way your car performed prior to discovering the head gasket needed to be replaced, by all means, have your head shop freshen the head. Your head shop will probably clean your pistons, oil pan and valve cover for a nominal fee. Find yourself a new head gasket, a set of rings, a set of rod bearings, and a set of head bolts, hone the cylinders, and you’re done. The small amount of time and money spent on a quick valve and ring job will last you for years. By all means, get a good radiator, or get yours fixed. I’m not so sure what the deal is with the improper holes in head gaskets. I enlarged the holes on my head gasket as seen below. Also notice the 4 large triangular shaped drain holes in the gasket. These 4 holes are under the lifters, and on the downhill side of the top of the engine. I damn near wrecked my head gasket enlarging the other 2 holes. Last time enlarging head gasket holes for me. My suggestion is that if you want to consider any services from 3Tech, assume there is going to be lead time involved. Personally, I have not used his services, but many others on this forum, and untold others have, and are happy customers. It could be a week, or a month. He'll get to you right after the last guy in line before you. At this point in time, PM is the best way to contact him. He post his prices. Send him a money order, a letter describing what you want, and wait. ![]() |

I'm with you on this one. After years of recommending that people open up those holes, I've come completely around to the other side. Those holes are for blowby gasses to get back up to the valve cover area in order to be whisked away by the PCV system. The occluding gasket material might even help keep some of the oil down, which is good. The oil drain happens all up front, where the holes match up just fine. The factory gaskets have the smaller holes too. And back on topic. I recommend doing the valves and rings as long as you are in there. If the shop says your head is good, have them do a quick lapping to freshen up the valve seats. Exhaust valves are the #1 problem with this engine. Edited by Woodie, Apr 14 2011, 05:58 AM.
