New engine?
I was just wondering what a new engine would cost for a 89 S-10 4.3 Blazer it has over 160000 miles. It runs great, but I have seen the inside which is full of sludge. I don't want to put too much money into a lost cause. The body is good and the tranny is supposedly rebuilt. Thank you for your time. Steve

Re: New engine?
What color is the Sludge?
If it's milky color you've got some water contamination, and it'll cost a little to fix . But still less than a re-build. If it's just dirty oil then your best bet is do an engine flush, and a oil change. I would consider doing another flush and oil change a week or 2 later, then start using Synthetic oil. It might take of your rear seal leak as well.

Re: New engine?
I had to do the Intake gaskets some time ago. Thats when I saw black crusty sludge in the engine. How big a problem is that? thanks!!!

Re: New engine?
You really should have done a engine flush then, but if you do like I sugested you should be fine for a while. The synthetic oil will really help keep your motor clean then and last longer

Re: New engine?
I can tell you that this year model engine has lots of potential , Mine has 246K on it now . Not sure if it was replaced or rebuilt before me but I was delighted to see roller cam followers when I pulled my intake off . If needed Advance and Auto zone carry reman units for around $ 1800. Twice what I paid for the whole ride . Seafoam might do wonders for the inside , though I have not tried it myself yet . Rob

Re: New engine?
Also , that sludge you are talking about on top of the cam between the heads is normal . Not much oil goes thru there . Just a drip or splash so it cooks down to the sludge . I cleaned mine real good with a putty knife and scraper vacuumed it out with a shop vac , sprayed it down degreaser pulled the plug and poured a couple of cheap quarts of store brand oil all down thru it to wash the parts and pan out . Then put it all back together . Rob
