hi friend .. when you put a piston in a wrong way the engine sound like that.....or the conecting rod whit the piston.is too old( bronce) the sound is like that too... is mi opinion. i hop to help you ... and sorry for mi poor english... se you..
Had the same problem, easy fix, harmonic balancer is off, banging against da side, aka, "wobbling" and that the sound your hearing. ( => its the biggest flywheel on the bottom that happens to be connected to the crankshaft, which also happens too be the outer wheel that the belt wraps around when your looking at your engine standing over it.) Stand over it with lights on and have your friend or yourself revv the engine and watch the wheel wobble and hit surrounding area. :)
hey man look what type of gasoline u are using, maybe this sound is because u are using the wrong gasoline grade, try with a different one like mid-grade, im learning mechanics for the armed forces and i think it would help.
Mine was making the exact same noise, took it to a 30+ VW pro, said its fine. I will run mine as my daily driver and I guess just see what happens haha. btw, it has less than 3,000 miles on it
near the crankshaft area??? because I have almost the same noise. I also adjusted the valves to no avail, and checked the rocker arm side-play. Don't really know what else to try.
that engine sounds mechanicly sound, no bearing mechanical issues, but when you lift refvs, i hear slight hint of a slight missfire maybe? like MrMrtiki said, i'd check your timing, other than that sounds sweet
Put a pint of Trans oil in the motoroil for one week too see if it has sticky lifters how long has the eng run without an oil change the trans oil is a detergent IT WILL NOT HARM THE MOTOR in anyway this will clean that ENG.up so fast you`ll wonder where the sound went in about 2 days I have been a ford BLUEBLOCK man for 30 yrs.noisy lifters are my specialty A beetle can run very hot and create a oil shale on the lifters this method WILL clean it up better than RISLONE uses Diesel for cleaning
@boaterbil I took another listen to this try a eng timing retard sometimes an eng will try to diesel itself with the eng too far advanced back it off 1 or 2 degrees the bug looks like you take care of it pretty good if an eng starts smoking bad do a comp. test if 1 cyl is low run that valve set late for 2 hrs back off lifter bolts 1/8 turn this richens the oil build up on the jug and valve seats this method can loosen them from the bottom FAST return valve nuts 1/16- 1/8 if noise goes away .
Ha ha.. get used to it! I adjusted my valves eternally and it was never quite perfect. This is why this type of valve and rocker isn't used today. Still it's a beautiful engine build. Nice job on the details.
its basiclly pre-ignition means the mixture is igniting before it should, which means its sending a shock through the piston and conrod through to the crank. it happens from using a fuel with too high a volitility and too low a flash point (ie low octane). higher octane fuel and correct timing fix it most of the time. don't fix it, say goodbye to all the high strain components of ur engine
@Bloodsteri667 knocking is bad because though an engine spins fast and parts move backwards and forwards and spin constantly, the tolerances between parts when connected should be practically nothing if a conrod isn't connected to the crankshaft properly, within a very short amount of time the action between the two will be like a hammer moving side to side between two walls (this equals damage) whereas the should be no play before the conrods action is reciprocated against the crank.
Ah OK, I was asking because my old 305's 1.5 engine also developed a "dead piston problem" at one point. It would travel with 3 pistons until you exceeded a certain speed, then the 4th would suddenly kick in ;-)
yeah I know that problem, same thing, you turn the car on first time and you can hear the non-working piston. I changed the spark plugs, the distributor cap, distributor arm and my pug works like a girl ;)
Sound like valve train noise, could be the valve lashing might be to lose. Pull the valve covers off and try to move the push rod up and down there should be no play in the up and down motion but lose enough that you can spin the rod with a bit of effort. If not the thicker motor oil could stiffen up the lifters and should quite down as said in other comments.
Possible one of the valves is too tight? Just a guess on my part, that hissing noise suggests either he has the exhaust work off or a jug is loose... or one of the valves is staying open.
I'm just going off the fact that my VW never did this while it was in working order.
it sounds like lifters but i dont know if your motor has any,sounds exactly like my fathers v8 wagon.just use 20,50 motor oil and possible will lubricate better
u r right but i say thats the valve clearance. when the motor is out of oil, the clearance will grow. or the valves ar easily wrong installed... same failure same noise
that's only if you're using a high compression engine. if you're using 7.5:1 you can run regular no problem. you might be able to do with with 8:1 but i dont' remember off the top of my head
ur valves need to get hot before they become the right size. so let it warm up
have u been keeping track witch valves have been tighting on u. cuz when u do and u notice 1 is tighting up all the time u need to change it cuz it going to blow pritty soon
they are always lubricated, you kidding me, even the pushrod tubes have holes for lubrication to the cam and rockers. Might be that you have hydraulic valves that aren't "pumping" up.
yea on those motors those valves tend to be the first thing that needs replaced. and that is prolly why its chugging like that . a burn valve maybe. but what ever it is it has something to do with the valves.
Aircooled engines tend to be noisier because there is no liquid to dampen the clatter. Don't overtighten the valves or you could burn the exhausts or cause backfiring into the intake.
should be just a problem of fuel. The bigger the droplet size, the more knock you have.

if you use regular, the compression ratio will cause the gas to combust before it is supposed to, and will make that noise
