How much does a 6.9L weigh? / Compression test question
Hi guys,
I can't seem to find a specification for the weight of a 6.9L complete engine... I think my engine stand is rated for 1,200 or 1,800 lbs. (I can't read the sticker any more). If I do end up pulling my engine I need to know if I need a bigger stand. I have a 3 ton chain pull to get it out, so that won't be a problem.
Also, before I make the decision to pull it, I want to do a compression test (see my thread about running low on oil), but I am having trouble finding an affordable compression tester for a diesel application. I actually only found one vendor, and the price was over $200 because it's a kit with adapters for many engine types. Is this par for the course or??? Seems like for that much I should just have a shop do it (if I can find one I can trust
) Seems like I read a thread here that mentioned a compression tester could be had for $40. I found gas engine testers for that price, but they maxed out at 300 psi, and the Haynes Techbook says the 6.9L should read between 220 and 440 psi. Does this range seem right? Huge difference between 220 and 440.

Fully dressed they run about 1100lbs. Get the biggest stand you can. Mine is rated for 2000lbs and it sagged pretty good. The comp test range is the lowest should not be less than 75% of the highest (some have seen up to 550psi). Spend more for a better tester, some of the cheapies don't last for more than a few cylinders.

I put my spare on a scale. Without alternator but everything else on, it scaled at 1291 lbs. It is a 1983, and I hear that 1985 and up are heavier due to internal stress webbing.
