nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 (edited) yeah she still runs and i know my shit dickheads i always make sure she has oil and coolant and at the time her fluid levels were right where they should be, the only thing that was defect with the engine is that i had a lot of piston ring blowby Edited March 7 by nathan.is.an.idiot12312 Quote Link to comment

nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 and the whole reason the rings are defect is because a previous owner bever topped her off Quote Link to comment

datzenmike Posted March 7 Report Share Posted March 7 If not apart you can't know what's wrong. If making a loud hammering sound a rod bearing is toast but the rod is still probably ok but the crankshaft is most likely toast. There may be enough rod clearance that the piston starts hammering the bottom of the head. If hammering and squealing, the bearing has welded to the crankshaft is spinning in and trying to weld to the rod and moments away from locking up. If going slow enough the engine just stops. If driving fast the rod and crankshaft weld together, the rod snaps off and punches a hole in the block and/or oil pan. Sometimes at the piston, throwing those pieces into the valves.  NEVER over heat an engine. If lucky all that happens is the head warps and you blow the head gasket. Keep driving, the rings expand, close the gap and break themselves and the piston, score the cylinder. ALWAYS keep full of water and oil and nothing will go wrong. Quote Link to comment

nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 and i mentioned in a previous post that it had been misfiring and sputtering a bit, it ended up being a vacuum leak and i was and the screach was from a missing engine mount bolt that had the rubber mount squeaking. i fixed both of these things 2 days. no timing issues Quote Link to comment

nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 she still runs and idles im not driving it again or running it until its rebuilt, im not stupid and there didnt seem to be oil coating anything in the engine bay or underneath the car so im pretty sure gas filled up the piston and didnt ignite, bending the con rod.

nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 given the fact i had low compression and less hot running spark plugs im almost positive it was that enough oil got into a cylinder to make the gas not ignite and bend the rod Quote Link to comment
nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 man i hate being a young mechanic in this generation, so tired of people undermining my mechanical knowledge and ability it pisses me off so much 2 Quote Link to comment
datzenmike Posted March 7 Report Share Posted March 7 You mean hydro lock? because that can bend a rod. Oil getting into the cylinder will just cause smoke otherwise. None of your rods are bent Quote Link to comment
nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 im pulling the head off when i get home ill keep yall updated Quote Link to comment

None of your rods are bent im saying this because i know oil has a much higher ignition point than gas and the engine wasnt all the way hot when it happened Quote Link to comment
nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 i stuck it in nuetral and coasted most of the way to oreillys and asked a retired mechanic that works there who works on older engines like the 22r all the time and he said it sounded like a bent rod Quote Link to comment
nathan.is.an.idiot12312 Posted March 7 Author Report Share Posted March 7 and i was running lower temp igniting v power ngk resistor plugs  Quote Link to comment
banzai510(hainz) Posted March 7 Report Share Posted March 7 (edited) labol everything.use vid camera take it apart  pull the motor and rebuild it/ or maybe rebearing rering it as a cheaper option.  lucky its a simple motor  either way its coming apart Edited March 7 by banzai510(hainz) 1 Quote Link to comment
jagman Posted March 7 Report Share Posted March 7 Nathan, If it is a rod and you have been having blow by problems you want to have a machine shop either bore or hone the block. They all have access to top of the line rods, pistons, bearings and rings. Check with a good machine shop for pricing. A piston slap can sound like loose rod too! When I got my chysler straight 8 disassembled we thought the pistons were swapping holes they were so loose. 1 Quote Link to comment
