Why does your engine knock on your 1998 Chevy 350 small block?
Engines can make many different noises and people will describe them as knocks, pings, rattles or thumps. A true "knock" is caused by rod or main bearings hitting against the crankshaft. The general cause of that is either too much space between the bearing and crankshaft or insufficient oil pressure to maintain the distance between the bearing and crankshaft. Sometimes you can use a heavier grade oil so that the oil doesn't leak out of the bearing space so quickly. If you're currently using 5 W 15, go to a 10 W 30 or maybe even a 15 W 50. If you can't make the noise go away with that, either the bearings are too worn or it's a different problem. If the engine has less than a couple hundred thousand miles, the only reason for bearings to go bad would be inadequate maintenance. Other problems that can result in noises like that are: Piston slap. That's when the skirt (lower part) of the piston is slightly worn and is enough smaller than the cylinder that the skirt "pops" from one side to the other as the engine runs. It's more of an annoyance than a real problem, especially since piston slap typically goes away as the engine warms up a little. It typically takes just a few seconds to go away. If it's piston slap don't worry about it until the engine is rebuilt. Piston slap is quite common among many of the GM 350's, especially in engines that go short distances a lot or don't get adequate maintenance. Fuel "pinging". That's when the fuel ignites too quickly and causes a sound like something rattling around inside the engine when you step on the accellerator. Use a fuel octane booster or change the engine timing. Hydraulic lifter noises sounds more like a tapping sound and is usually caused by inconsistent oil changes.
The Vortec 5300 (325.1 cu in) is a GM V-8 truck engine. Vortec 5300s are built in St. Catharines, Ontario and Romulus, Michigan. First introduced as Generation III in 1999, the Generation IV Vortec 5300 engines share all the improvements and refinements found in other Generation IV engines. At present, six versions of the 5300 engine are in production: 3 iron blocks (LY5 LMG, and LMF) and 4 aluminum blocks (LH6, LH8,LH9 and LC9).
Yes it will fit right in there. A small block Chevy is a small block Chevy. The only thing that is different is the fuel system. All small block Chevy engines are the same it does not matter. Chevy did not redesign the engine blocks until late 2000. But in your case the 2 ingines are the same. Put it in there.
usually on the side of the engine by the crankshaft. The knock sensor provides the computer the position of the crank shaft to give it the right information to get correct timing. A bad knock sensor will cause it to run ruff or not at all The knock sensor senses spark knock or pinging and sends that info to the ecm. The ecm then in turn retards the timing until the ping stops. You can…
I'm not sure why you'd want to put a small block Chevy in that Pontiac. But some things to keep in mind....most of the engine wiring is on the opposite side. You'll need to change engine mounts on the frame and you'll also have to make sure to get a Chevy transmission as the B.O.P.C trannys won't bolt to a Chevy.
It sounds like you want to know how to change the engine in a 1970 Chevy truck from a small block to a big block. If that is the case; there is no difference in the mounting of the engine to the transmission or motor mounts. The exhaust system will need to be changed, and the small block radiator might not be big enough to handle the extra heat made by a big block when…
