@tennuteproject, where is the noise coming from?
The easiest way to find out is to grab a 1m section of garden hose and put one end to your ear and move the other end around the rockers, heads and the sump and you should have a much better idea of location... Just be sensible and keep the hose, your cloths and body parts away from spinning bits and it should be ok...
If it sounds like it’s only at once rocker, pushrod or lifter location that is noisy, it could be repairable, though you’d need to evaluate how slugged the rest of the engine is (take off a rocker cover, or take off the oil filler cap and look inside the engine if possible)....
But if you think it’s too way too slugged and want to replace the engine, what’s to loose trying something rather radical?
As a radical step, since rim borded today, consider dropping the oil, disconnecting the battery (so you can’t start it) and then fill it up to the very top with safe low VOC paint thinners ($100 for 20l?) or kerosine (since it’s not as harsh on seals?). Leave it soak for a week and then drain the cruddy fluid well.. maybe even blow compressed air in through the oil filler cap with sump plug removed to get as much of the stuff out (may be use rags to catch the crud coming out of the sump as it could make a mess)... Then fill up with clean cheap oil to the correct level, chuck on a cheap filter and connect the battery then start the engine. Hopefully oil pressure will built up quickly so listen for any noises. If it’s worse, you‘ve just lost the cost of the thinners, some cheap oil and filter...
Hopefully the sound is not as bad as before and it’s actually improved the situation, in which case let her get warm and then dump the oil once again... Depending on the improvement, you could try and repeat this automotive colonic cleanse a second time, or just fill up with cheap oil and another cheap filter and go for a gentle long drive b4 dumping it again and doing a final fill of cheap oil and filter.
Who knows, if it’s just a stuck lifter, maybe just maybe, doing the above could be enough to clean it and the sludge out and make it quiet again... maybe... Obviously, if it’s better after the first or second cleanse, and the oil changes, drive it around for a while before trying a flush additive and finally filling up with good oil... If it hasn’t worked pull the engine and take off the front cover to find out how well the method actually was at cleaning things and to find out where that noise was coming from
Video tape the whole process and stick it on a youtube channel you create and everyone on the www will know if such an automotive colonic treatment actually work or not. If you get millions of hits you’ll make $$$ otherwise you’ll have thrown away a throw a couple of hundred $... and given us all the answer we always wanted
PS: on these forums,
@losh1971 changed his lifters and put the stuck lifter in a jar and had it soaking in thinners. After a couple of weeks, it loosened up enough he could dismantle it... Once cleaned the lifter was ok so was stored on a shelf.
