Johnny93 Posted April 18, 2022 Share Posted April 18, 2022 Does anyone make head studs for the EM6-300 engines? If so could someone provide a part number or a part number for head bolts? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/ Share on other sites More sharing options...
Joey Mack Posted April 19, 2022 Share Posted April 19, 2022 AGkits.com.. are you working on a 20 bolt/ head engine? or an 18 bolt/head engine? jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495599 Share on other sites More sharing options...

Johnny93 Posted April 19, 2022 Author Share Posted April 19, 2022 Thanks Joey! Is that part # for head studs or head bolts? Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495646 Share on other sites More sharing options...
Joey Mack Posted April 19, 2022 Share Posted April 19, 2022 studs... i cant post any more pics, otherwise you would have seen the package I have.. the nuts may be an issue.. so clean yours really good for re-use, the thick washers may be found a bolt supplier... jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495671 Share on other sites More sharing options...
Joey Mack Posted April 19, 2022 Share Posted April 19, 2022 So I just re-read your post... Do you have a 2 valve or a 4 valve E-6? jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495673 Share on other sites More sharing options...
Johnny93 Posted April 19, 2022 Author Share Posted April 19, 2022 (edited) I haven’t pulled the valve covers to find out if it’s 2 valve or 4 valve yet, it’s a 1984 EM6-300 it looks like factory it had head bolts so I will need studs, washers and nuts. I would definitely like to put studs in it when it goes back together if I can get some. So far every website I’ve found and called they only have a few on hand, none of them have 40 bolts in stock.

Joey Mack Posted April 19, 2022 Share Posted April 19, 2022 its a 4 valve... why do you want studs? the head bolts in it are good to go... jojo 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495681 Share on other sites More sharing options...
Johnny93 Posted April 19, 2022 Author Share Posted April 19, 2022 I’ve just always put studs in all my Diesel engines to help keep from blowing head gaskets. According to the odometer this engine has over 660,000 miles on it, I’m worried about the head bolts stretching with all the heat cycles they’ve had on them. The truck currently has a blown head gasket on the front head.

63BMack Posted April 20, 2022 Share Posted April 20, 2022 The older engines had studs can't remember when they started using bolts, I have seen broken studs I had one on my 315. Went to bolts hadn't had a problem. Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495685 Share on other sites More sharing options...
Joey Mack Posted April 20, 2022 Share Posted April 20, 2022 I do not know of a stud kit for the 4 Valve, not saying there isnt one, just dont know.. Mack did a good job with head studs and re-use was ok.. torque to 205- 210. you should be good.. I expect other opinions to show up here, but I bet i'm pretty close.. jojo Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495693 Share on other sites More sharing options...
Johnny93 Posted April 20, 2022 Author Share Posted April 20, 2022 I seen a couple different posts stating some information about how to tell the difference between 2 valve and 4 valve engines, I’ll copy and paste the posts I seen. “The 2 valves have external injectors seen on the drivers side of the head The 4 valves have the injector lines that screw into the head on the pass side.” “Steel valve covers 2 valve aluminum valve covers 4 valve.” I’m not sure how true those statements are but with that being said, my engine has the injectors exposed on the drivers side and it has steel valve covers. So I’m pretty sure it’s a 2 valve engine 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/69561-em6-300-head-studs/#findComment-495699 Share on other sites More sharing options...

Johnny93 Posted April 20, 2022 Author Share Posted April 20, 2022 Awesome, thank you for confirming that Joey.
