Tired of fixing lousy engineering.
99 K 1500 Suburban.
She started knocking really obvious today, occasionally squeaking instead of a knock. Knocks both cold and hot. You can hear the knock really obviously if you steth the exhaust manifold near Cyl 6&8.
Pretty sure I have a bearing that's spinning like CNN.
So either I'm looking at an engine swap or parting out. Shifts well, 4wd works. Trans fluid stays clean. Rear end a little noisy (slight gear moan, not bad bearing scrape).
Never did an engine swap. I have rebuilt a 10 bolt rear end before, a couple head gaskets. Just not sure if I want to dump all this time into this truck.
Open to suggestions. 5.3's are easier to come by, are these trouble to a less experienced wrench turner like myself? Especially on a 4wd.
Backstory for those interested:
1999 Suburban 5.7 with 240k. One of the previous owners apparently ran it with small/moderate amounts of coolant in the oil for a long while. My friend bought it from an impound lot, put 2k miles on it and parked it because he realized what was happening, as it got worse.
He gave it to me, the knocking wasn't apparent. I drove it gently home, diagnosed the low compression on one of the cylinders. Installed reman heads, new injectors in Dec 2017.
Was my first cylinder head job, and since I got two years out of something I paid about $1k in parts for, not a bad deal. A year later I had to do my wife's truck (same thing, 99 Suburban).
