Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Yes that is indeed very interesting. I appreciate you posting the link. I will keep this in mind when I go to dropping the P400 in place. If the girdle or pan will not clear the OEM crossmember I will try to compare the ORD part to that beast and see if either will provide clearance. I AM running crossover steering so I will have to keep that in mind. I anticipate things to get a little dicey on engine-install day.
That sucks! Can't wait to see what's next tho!
What a bummer. I am assuming you will tear down that engine to find the problem. What block do you intend to pursue? Rebuilt or new?
Could be a bad injector! Waiting for the pop pressure tester to find out!
No worries! I fix everything! 2insane makes it all better!!!
Just remember surface temps are not internal temps. The only way to get really accurate numbers is to install temp sensors in the coolant passages. I assure you that the rear of these blocks run VERY hot. Simply dropping system temperature will NOT change that. In fact by lowering the temps below 220F you are losing power, getting incomplete fuel burn and fueling your oil which can lead to lubrication issues. Diesels need heat to burn properly.
Thank you!
Thanks for the update.

Thanks for the reply. Just so you will know, and for the benefit of all SS members who may happen to read this, the Bostic engine is not a NEW GM engine but instead is a remanufactured unit. I hope you enjoy good service from your engine, as there have been others who have not. Maybe some of those folk will chime in, but for me, I will not comment further.This Optimizer NAVSTAR is a long block. (Not Fully Dressed with accessories)

GM 6.5 Diesel Engine - The Optimizer 6500
The 6.5L GM diesel engine was introduced in 1992 to replace the 6.2L diesel engine and was in turn replaced by GM’s Duramax 6600 in 2001. On the surface it would appear that the story of the 6.5L diesel would end here, right? Well, that wouldn’t make much of an article. Related Articles - The
Bostic Motors claims they have never had any of their Optimizers Crack with over 100 Optimizers sold. I checked their reviews and it appears their claim is legit.
It may not be fresh from the factory but their reman process is good! Practically a new motor if not better. Here’s more info:
| The pictured engine fits 92-2001 Chevy & GMC C/K Series trucks w/ GM 6.5L Turbo Diesel (Sidemount Turbo). This is a re-manufactured engine using Genuine AM General / GEP Optimizer™ / Navistar™castings..... the ones built after 2004 with the better castings. This engine will also fit all Non-Turbo applications, Pickup Truck, Van or the H-1 Hummer. This engine can also be built to service all Center-mount or Rear-Mounted Turbo applications, (H-1 Hummers , Vans & some RV's). For over 21 years now, we have been involved with the 6.2L and later the 6.5L engine exclusively. Check out our Feedback! People love our products and service! Some other companies are selling new block/head engines, but be careful, most are new block/heads using the old casting forms, no improvements - FROM CHINA! . Booooo! There is only a handful of others offering IMPROVED & UPDATED castings aside from AM General and General Motors themselves. The design improvements and re-engineering of the improved castings add durability and virtually eliminate the potential for cracking in both the block and heads. Here is What is New and Improved about our Engines: These Engines Are Built Using the 2004+ Optimizer™ / Navistar™ Improved Block & Head Castings. Our engines also include major improvements to the oiling systems, including our exclusive: High Volume & High Pressure Oil pumps. BLOCK & HEADS: The iron used in the new block utilizes molybdenum, a metal yielding a 20-25% increase in strength, without being brittle. The new block design also incorporates improved main bearing webs and caps. In addition, the head bolt holes in the block deck are strengthened, vastly improving head gasket durability. Additionally, changes of the water jacket design in the heads have helped address the 6.5's overheating problems. The original 6.5 & 6.2 cylinder heads produced by GM were prone to developing small cracks between the valves. The new redesigned heads have added chromium to the cast-iron to virtually eliminate these and other cracking issues. The Optimizer™ block and head system offers complete parts interchangeability & bolt hole alignment as your original block. OILING SYSTEM: This engine also gains improved durability & longevity with a High Volume / High Pressure oiling system. INTERNAL COMPONENTS: We use MAHLE Clevite branded internal parts on both our new and remanufactured offerings. These are top quality parts from a well known industry leader. AM General and GM both use/d MAHLE as the O.E.M. internals. Mahle Clevite has significantly improved both the Pistons and Connecting Rods since the time that the 6.5 was used by General Motors. The Connecting rods are more durable and the Pistons are stronger and lighter. With these important improvements, the BMI 6.5 is among the toughest 6.5L diesel engine available today. We have have been selling the 6.5L engine with new improved castings for more than 9 years now with great over-the road success. Now we can offer the Real Optimizer™ castings! Not one block or head crack issue to date. - Now that's what we mean by an improvement. Compare to others: Our longblocks come with already installed; Valve covers, Oil pan, Oil Pickup Tube, Timing Chain Cover, New Harmonic Balancer. Every one of our engines are hot-run in on the dyno after final assembly. During this time the camshsft is properly broken-in, the and the engine is monitored for any sign of oil or coolant leaks. All of our engines are dyno tested. This is why we do not offer short-block engines, Short-blocks can not be adequately tested on the dyno. Be assured with our Unlimited Mileage, one year warranty covering every engine we sell. You expect hard work from your diesel powered truck, and we'll guarantee it. We are proud of our long track record with the GM 6.5 Liter Turbo Diesel engine. We do not take shortcuts during the manufacturing process.
