I just arrived home from work last night so hoping to get back at the 5.7 diesel tomorrow and do more work on the truck.I bought a nos gm water in fuel option for the 78,79 trucks that didn’t have the water in fuel light.The kit I bought has the light,wiring harness and new fuel tank sending unit.

I purchased a new gm crank sensor for the 6.5 diesel this morning.I have the 6.2 with the DS4 but these sensors are going at a good price and seller has quite a few left. https://ebay.us/m/70ynAJ

I checked that measurement out before I installed the hydroboost.Both of those steel pins are the same length when I did the comparison so I should be okay.The 1979 hydroboost pin was the same length.It was just the long rod that attaches to the brake pedal lever was too short on this newer...

I had to make a bracket so the hydro boost pushrod could be attached to the brake pedal lever.Seems this newer hydro boost fits the 90s gm trucks instead but I was able to make it work out okay.I reused the original hydroboost firewall mounting bracket from 1979 which worked out good also.I did...

Thank you will👍

The injection pump is a reman unit with updated governor assembly so no flex rings to worry about.Both the injectors and the pump itself have been sitting for several years without being used so I think a good run on the highway will improve things.

I did buy a set of 8 several years ago in gm boxes but I had trouble with two right from the start.So I had them checked and the shop found two out of 8 that were faulty.So they sent me two reman injectors.As of now the engine has a slight rough idle so I just figured once the liquimoly cleaner...

Today some archoil diesel injector cleaner arrived from Amazon and another serpentine USA made belt for my 5.7 diesel.I look forward in using the archoil product in the 5.7 and my other diesel vehicles.I read archoil is a good product.

I may of heard of that product before but I have’nt used it.The balancer and pulley are back on the engine and torqued in place after using some loctite.I’m looking forward in getting this truck road ready.I don’t have much more to do with it but I’m pretty eager to start driving it again.Its...

The shop called today saying the collar is ready.Heres a picture of what it looks like.There isn’t much to it but I’m going to use larger outside diameter flat washers so the collar/ring doesn’t decide to work loose and fall out.Its a tight fit though.I had the pulley off and the collar is...

I did a lower driver control arm removal on my 96 K1500 but it had the stamped steel version.I didn’t have any problems with the clearance getting the bolts out past the differential.Maybe I got lucky for some reason.I reinstalled new moog AWD astrovan control arms.I like them.They fit...

You are indeed right.I used arp main studs on this olds engine.I probably should have used them on the heads but I’m sure the arp head bolts will hold up okay.

I would only use flat hardened washers also.It would probably of made a huge difference under the gm bolts.

Here’s a old picture I found of the 5.7 diesel using CAT head bolts.You can see the cat stamping on a couple.They are the 1/2-13 like what gm used back in the day.I find hardened washers under CAT head bolts if anyone decides to use them makes a huge difference.

lol😂

Yes I have seen those.I always liked those CAV units.

I got hooked into these engines because my father bought his C10 back in 1980.Its a 1979 but the original D block snapped a piston pin gouging the cylinder wall so I was interested in finding another 5.7 diesel to go back into the truck when I became old enough to work on it.I’ve been hooked...

Pictures will be on the way soon when the machinist says the collar is ready to be picked up.I’m eager as well to get it back…lol

It’s the relay I bought on eBay.You are right.Its a mid 80s 6.2 relay.A delco remy unit.
