According to MapQuest we are 3 hours, 2 minutes or 171.70 miles apart. I planned to use the motor as a project for a buggy of sorts or even a tractor but I am wayyyy too ambitious. I could use the garage space anyways.

Well I have a reciept for the engine that is dated 2-14-05. I states that it is a used 300SD engine. There is a place where the PO signed that reads,"Buyer has inspected and accepts the goods "as-is". " It has the IP, turbo, mamifolds. What I know it is missing is Alternator, A/c compressor, glow plugs, water pump and the valve cover nuts. ( I did a valve adjustment on it first before I did it on my daily driver) Thats just all off hand. And what I paid for it... it came with the car. Which was a cost of $2100.

so here is the situation with the engine. the head is about 100% shot. broke the cam and the first three cam towers. these are robust engines. so i am pricing the least expensive options for the car now. i have two.

1. get the engine from young.

2. try to find a used head.

what would be the best option?

i'll take some damage pics an post them at a later date. if there is one think i have learned from this it is... if you hear the timing chain start to slap STOP.

it is hard to describe. you know the normal tick tick tick of the engine, it is like that but it is very noticeable from the very front of the engine. i would almost say that it is a similar sound to slightly low on oil but alot louder and does not go away when you add oil. this was the first time i have expierenced it and knew what it was straight away but thought i could limp it the 60 or so more miles i had to go.


as far as chain mileage, i don't know. i assume it is the original with 329,3XX on it. when i adjusted the valves i checked the chain stretch via the cam marks, lined them up as close to perfect as possible. had a helper watch the marks while i gently tapped the cranksaft moving it a few mm at a time. it was only at 4 degrees of stretch.

everything in there was nice and clean. the lobes loked as if they are or were new, chain was shiney. i don't really know what happened, but i do know that i am in the market for a replacement now. it sucks cause it still had loads of pull even after the speedo pegged. pulled nice and hard up to 4200 rpm or so.

*edit*

two more things...

1. young what is the engine from? is it a 617.950,1,2?

2. has anyone done a DIY on a 617 head replacement? If not i am doing the work and will make one.

My timing chain used to slap upon start up until the oil pressure built up - the tensioner wasn't pumping up. I went ahead and replaced it and that fixed the problem. I'm still curious to know what caused your chain to break. I wonder if its even possible to tell. I hope everything works out for you.

I am pretty sure it is from an 81-84 SD. No 85 because there is no emission garbage on it and what not. It does not have the suspension pump on the head so its not from a wagon. Thats about all I know.

well the tensioner is fully extended right now. i can see part of the chain on the drivers side. there is shrapnel (sp?) in there, and wedged beween the teeth on the cam gear there was a piece of a circular thing. maybe 1/8th of an inch in diameter and an inch long.

Yup, chain let go, probably due to excessive wear and/or a bad tensioner.

Most likely the rest of the engine is fine, just needs a cam and cam towers. Nice that they let go instantly -- you didn't hear any noise because the cam pushed up and no longer operated the valves once the first one hit.

Get a new cam and towers and get a new chain in it (and get it timed) and it's probably fine.

i am going to say a bad tensioner. i checked the stretch and it was only 4 degrees, so i kinda doubt the chain was bad.

i hope to everything holy that i don't need new pistons.

Probably don't need new ones but a valve might have been bent
