The head gaskets can fail on the two bolt engines, especially if a head bolt loosens up.dansmg said:re-plumbed the tank and made sure the cap is venting. Plastic intake? good thing to check. I did tighten the bolts but havn't tried to run yet. DDM thought maybe head gasket...
i had repeated leaks on the 2 bolt engines until i went to ddm graphite- stainless steel- trick is to this type of gasket- ya gotta torque- and idle a little bit-retorque- run the car a few moments- retorque agan- the graphite has to settle into place.- this worked for me anyways-- I use no loktite on the bolts- I use this type of bolts- HPI # 15438. wide head torx screw. m-5 x 20 mm. no washers-just the bolts.Ildy666 said:+1 on head gasket problems.i had same issues with them.
Idle is all over the place.Guantanamo Joe said:Ive had head gasket issues... during any run time, did you ever notice it all of a sudden high idling?
Crankcase bearings are bad also. Will have a new engine when it is is done. I do believe the motor was a lemon to begin with. Oh well. Learning how to rebuild an engine.dansmg said:Well here I am, with the truck 3/4 of the way apart. Head gasket is bad. Only about half of it left. Replacing head and also crankcase gasket. Of course fixing anything else as it comes along. I guess a little tear down maintainence is a good thing. Finding lots of loose screws. It will be better than mew when I get done with it.
all back together. going to test it tonight. wish me luck...Deluge said:Bad crank bearings, as well? Bummer.
