JIPJOBXX Posted February 10, 2010 Report Posted February 10, 2010 Well something went south in my engine as I just took a compression check and the first two cyclinders really out for the count. I hope its just a head gasket as that makes the most since as it was running really good and then this happened. I hate to take the head oft but it looks like I'm going to haft to do that. Is there anyway to check what going on under the head without taking it oft? I can see the vlvs are going up and down and there is a little compression but not much. Need some help! Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 There is no water in the oil and I have 90 plus lbs on all the other cyclinders. I did notice that I had to add some water yesterday so just maybe its a blow head gasket. Just one more thing to play around with. I still have a new head gasket I got a few years ago and so I'm in good shape to take it apart. Quote
Jerry Roberts Posted February 10, 2010 Report Posted February 10, 2010 If you can see the valves closing with the side cover off , then you need to pull the head . Probably just the head gasket as you mentioned . Before you replace the head gasket use a straight edge to see if the surfaces are flat . Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 I think I will just take it down to a shop and have them mill it. When I had the engine rebuilt I just check the head with a strait edge and it looked good but maybe it wasn't but that was around four years ago. So it was running pretty smooth yesterday but not in the mid range and when I got back from my haft a block test it was sort of missing again. Well I know all about the carberator and the egnition and now its back to wrenching. I did pour some oil in each of the two cyclinders and still very little compression. Darn I really didn't want to pull the head but well I got to do that now!! guess it will take probably a two hours or to get it oft. Jon PS. I did have the rotor out today and I thought I put it back in right where it came out position. But who knows maybe I mist it and it backfired just enough to complete the blown head gasket by by. I was just checking with my pressure gage and thats when I noticed that the two cyclinder were down for the count. Quote
aero3113 Posted February 10, 2010 Report Posted February 10, 2010 Did you ever change the head gasket or rebuild the engine since you had the car? Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 I did notice condinsation coming out the exhaust but I attributed that to being cold outside but maybe it was just the cooling water making it way back to the exhaust tip. Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 Yea the engine is completly rebuilt except the head. It has great compression on the four that are up and I suppose its just a head gasket. Engine cost nearly 1800 dollars to rebuild and it should only have around four or five thousand miles on it if that. Quote
thrashingcows Posted February 10, 2010 Report Posted February 10, 2010 Try using a compressed air to load up the bad cylinders. It should blow the piston down but then hold air, to some degree. Have the rad cap off and if you start seeing/hearing bubbles, or the water starts to flow out of the rad...then it's a head gasket. Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 Here it is and ready to take head down to have it machined. Not to bad to remove took about hour or so but of course all the bolts were put in with a special lubricate so that if I had to take it apart again it would come apart easily. That oil you see is the oil put down the spark plug hole to see if I could get any compression. Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 This I hope will take care of the miss I was having it must have had a small hole in it and then when It back fired it just blew the rest of the gasket out of way! Oh well I really got to do some supered ignition work and became a carburetor expert. Just what I need to have more useless information. Quote
aero3113 Posted February 10, 2010 Report Posted February 10, 2010 Good deal, I am glad it was not the same as Jims you will have her up and running in no time. Don't forget the torque pattern on the head bolts when you install them. Quote
jd52cranbrook Posted February 10, 2010 Report Posted February 10, 2010 Tough luck Jon, but a easy fix. Most common place to blow a gasket, either between 1 and 2, or 5 and 6. You'll be on the road in no time. Quote
Niel Hoback Posted February 10, 2010 Report Posted February 10, 2010 No information is useless, especially if its about your car. Quote
Joe Flanagan Posted February 10, 2010 Report Posted February 10, 2010 Wow, Jon. That is one blown head gasket. Any ideas what caused it, since it's relatively new? Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 Nope I kind of feel it had maybe a weak spot in it and when I back fired the car today it just blew it out! I'm taking the head tomorrow over to a machine shop to have them check it out to make sure it true and flat. Wish I would have done this the first time but that was probably 10 years ago and I just put a flat edge on the head. So now I have a little extra time to clean up my big mess outside and maybe repaint some of the engine compartment stuff. Quote
Frank Elder Posted February 10, 2010 Report Posted February 10, 2010 You should have them true the deck on the block also. Quote
martybose Posted February 10, 2010 Report Posted February 10, 2010 You should have them true the deck on the block also. Before you get too deep into machinework, answer this: How tight were the headbolts at the front 2 cylinders? When the head gasket went out on my original motor, I found that the bolts for that cylinder only had about 5 lbs. of torque on them, and when I put the new gasket in I had to retorque the headbolts 3 times after warming the engine up before they stopped moving. You may not need any machinework! Marty Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 They trued the deck the first time so I know its ok-Jon Quote
greg g Posted February 10, 2010 Report Posted February 10, 2010 Typical failure spot, the pistons were trading compression, so that'w were your high speed miss was coming from. not apparent at low RPM. Cylinders and valves look to be in good shape. Don't forget to retorque after getting some heat in it at restart. Quote
Frank Elder Posted February 10, 2010 Report Posted February 10, 2010 They trued the deck the first time so I know its ok-Jon Good deal. Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 Head is being machined as I type away! It was about .020 out so they are going to skim cut maybe .040" flat. Cost 50 dollars but well worth the money spent. Quote
JIPJOBXX Posted February 10, 2010 Author Report Posted February 10, 2010 By now most of you have heard about one of the Captains on the Deadliest Catch TV show. I just would like to pay a little tribute to a man who to me was a true American. Captain Phil Harris showed me that life is what you make of it and he presented that by being such a wonderful person to his children, life and work. We all go through life in certain manners and we all have our up and downs. To me Mr. Harris had the zest for being his own person but also seem to have a great love for his children. Life is so short and what more can we do but hope and pray that our children will grow up right and be fine honest Americans. Phil god took you to soon (53 years) and you will be mist by many and I thank god for letting me part of your life even if it was just watching your true presentation on what a true American can do with life. May god be with Captain and a breeze be in your sails -Jon Quote
JIPJOBXX Posted February 12, 2010 Author Report Posted February 12, 2010 head is back on and tomorrow its light oft time:D Quote
55 Fargo Posted February 12, 2010 Report Posted February 12, 2010 Jon, did you start this engine up today, and see how things are? Quote
