edekalil Posted August 2, 2015 Report Share Posted August 2, 2015 OMG! After checking the 70/510's compression the front cylinder has 0 compression. I guess that is why the car has less power and that strange exhaust leak sound. I guess a valve is not seating or is stoping just before seating. Another thing to sort out. Quote Link to comment
datzenmike Posted August 2, 2015 Report Share Posted August 2, 2015 Check valve lash first. Then... Broken spring. Burnt or bent valve Valve seat has fallen out Hole in piston 1 Quote Link to comment

edekalil Posted August 2, 2015 Author Report Share Posted August 2, 2015 Thank you all for the info, I will put it to use here soon. The car ran good and strong before this issue, hopefully she will be running strong again soon. Quote Link to comment
edekalil Posted August 2, 2015 Author Report Share Posted August 2, 2015 Wel look at what I found. I can't say I have had this happen before. I took a big screwdriver and popped it back into place and then there was compression in the cylinder. A little lower than the others but it probably been running like this for a while, not a great while but a little while. I took it for a short ride and she ran way way better it has a little tap but an adjustment should help that. And after I run it a while I will check and readjust it if needed. My guess is it will get better. 3 Quote Link to comment

The 72 is now running like the days of old, I even took it up to 70 on the interstate for a while today that was exciting. I believe the 70/510 here will be doing much better very soon.

edekalil Posted August 5, 2015 Author Report Share Posted August 5, 2015 I drain my tank every 2 years if I have stabil, car not driven much Hopefully I will not have to go that rout. I do drive them most weekends I am home. They only sat for a while way back when I was having seizures. But all is ok now with that and the cars are coming around and do get driven regularly. This is the first time I have had a fuel issue like this so hopefully it won't happen again. For sure when I put the motor in the wagon I will drain the tank of any gas or funk before I use the car. It will be easer being that the plug is outside the car. Quote Link to comment
