This one has me stumped. On a cold start, my 97 D1 idles ok, but sputters and barely drives above 5mph until the engine is thoroughly warmed up, at which point it runs excellent like nothing ever happened! This issue wasn?t something that was slowly building up and running more poorly over...

Vehicle: '97 D1 XD Symptom: Some brake lights work, some do not. The brake lights on either side of the rear door do not work. The one on top of the rear door does work, as do the brake lights on a trailer when hooked up. Attempted fixes: I checked the bulbs - they are fine I replaced the...

I have a fresh LT230Q ready to go into my '97 D1. I picked up a used unit that was pretty clean (thanks RoverDude) and am resealing it with fresh gaskets, o-rings and Right Stuff just to make sure there are no leaks. When I went to reseal the intermediate shaft I loosened the nut and slid the...

My wife had my '97 D1 XD out yesterday, broke down and needed a tow home...sigh. Apparently the transfer case or transmission oil light temp went on (looks like a red gear with thermometer in the middle on the upper left part of the dash). She stopped and it went off. After another 30 mins of...

Hey guys - Cleaning out my garage (ugghhh) and have some things I do not need anymore: D1 4.0 engine w/ about 110K on it - dismantled, heads still on block - it ran fine when removed (I put a 4.6 in mine, that's why) D1 Transmission w/ about 90K on it - rebuildable (internal clutches burnt)...

duplicate - sorry

How much play in the timing chain is too much? When I rebuilt a 4.6 and used new chain and gears supplied with a performance cam kit (D&D), it was a nice snug fit - zero side to side play in the chain. About 16K miles later I pull off the timing cover to replace it (had a leak), and noticed...

Hi - just threw in a new fan clutch in my D1 - Hayden 2786 Heavy Duty, and wow is it loud. Mine was shot (could stop it with your fingers when its warmed up) so thought I'd upgrade to the Hayden. It seems that thing is always fully engaged, even high RPMs, when warm, cool, all the time... Is...

Anyone have one they want to sell, preferably lower mileage on it? ...or know a place that sells remanufactured ones? Oh, I live in San Diego, CA and need it before the weekend..! Thanks, Brian

Hi Guys - Just threw a rebuilt 4.6 into my D1 and used a cam sensor that was about 5 or so millimeters shorter than the original one. I cracked the original on the cam sprocket rivet from D&D...so I threw in a cam sensor from a p38. Maybe since it's shorter it can read the cam sprocket...

I followed the procedure on torquing the connecting rod bolts 15Ft lbs and then go another 80?. Out of curiosity I put the torque wrench on to see what the final torque value is and it seems to be in excess of 50ft lbs - does this sound about right? Anyone have experience with this? ps- I'm...

I'm slowly rebuilding a 4.6 and am now to the oil pump. It's measurements are within spec, but it seems pretty scored. The scoring is not deep but it's not smooth either. The housing looks fine (very, very light scoring only in a couple small areas. Does this look OK to throw back in or...

Does anyone here know how to line up the ring gaps on a 4.6? I've heard of multiple ways to do this...but the way the manual says to do it does not make a whole lot of sense to me....and the illustrations don't seem to make it clear either. When looking at the arrow on the top of the piston...

Is it common for liners not to be 100% flush with the cylinder deck? I have one that is just barely below the surface. Not sure if this could lead to an issue but thought I'd ask........... see pic. I recently picked up the used motor from a wrecked P38.

I had my cylinders honed and got a new set of rings. When I got the stuff back from the shop the pistons were not labeled as to which cylinder they go back into. The guy told me it would be OK since they honed the cylinders and I am putting in new rings (& bearings). Does this matter or...

Since I have my 4.6 completely stripped and cleaned I am thinking about securing the liners to prevent slipping. It looks like top hat liners or pinning them in are the more common methods. What about putting one or two aluminum spot welds at the base of the liners (on the block itself) to...

Anyone know if the 50229 cam will cause me to fail emissions in CA? It will be going into a freshly built 4.6. thanks!

Hello, I am getting conflicting reports about a Crower 50229 cam not working in 4.0 / 4.6 blocks due to the end of the shaft being different. Can anyone validate this, or point me in the right direction of a similar spec cam that will work in a 4.6? I am in the midst of rebuilding a 4.6 to...

Does any one here know of a decent machine shop in San Diego area? I'm rebuilding the bottom end of my 4.6 and as tempting as it is to just slap in new main & rod bearings I thought it'd be worth it to have the crank journals polished and have the bearings matched if undersize is needed. Some...
