I think it used a lot of the E9 components. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70593-if-you-had-the-opportunity-to-redesign-the-mack-chassis-and-the-mp-engines-what-would-you-change/page/6/#findComment-514038 Share on other sites More sharing options...
fjh Posted October 30, 2022 Author Share Posted October 30, 2022 11 hours ago, Onyx610 said: Was there any issues that you guys saw with these engines? The E9 had its issues! Valve seat issues / Lifter/ Cam failure, head bolts would break head gaskets leaked. piss poor engine brake this is a case of failure By design the brake as we all know has always been sort of ho hum on most Mack engines up till the power leash , water pumps failed a bunch at the begining! As usual Most of the issues resolved Before the end of the run on these ! The other weak point on these was the counter bore ledges would sometimes crack ! In my opinion the head bolts were under sized An really should have been fine thread and or studs! Thinking back on it How ever the 866 had fine bolts and they would leak also! they also had the liner ledge issue! If the big Six had entered production I would have hoped they would have used the E7 style liner set up but who knows ,it never got off the ground! also notice they left room for the econovance there in that design they were a forward thinking bunch of guys! But they were working with stuff they mostly already had they were working on a budget in my mind! That's likely why it never got finished! Money constraints ! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70593-if-you-had-the-opportunity-to-redesign-the-mack-chassis-and-the-mp-engines-what-would-you-change/page/6/#findComment-514044 Share on other sites More sharing options...
The Rubber Duck 006 Posted October 30, 2022 Share Posted October 30, 2022 If there's one thing on my 2016 CHU613 Pinnacle I could change it would the steering shaft linkage set up. The plate it hooks to blocks convient access to the alternator and such. Also I would give the MP8 atleast 500horse out of the factory. Other than the DPF emissions junk I'm very happy 😊 with the truck overall.

Onyx610 Posted November 11, 2022 Share Posted November 11, 2022 (edited) I drilled it a size smaller than that fitting and wrenched it in and epoxied it in there. If it doesn’t I’ll get a metal cap and cut threads. What do you mean by filter??

Joey Mack Posted November 12, 2022 Share Posted November 12, 2022 I would probably use a CAT Hyd./Oil filter..

They're thick enough to put up with considerable PSIs for testing when you thread a hole drilled through it. Easily can hold enough to check for leaks.....and it's a cheap way to test.
