Engine not running correctly after rebuild
I'd need to know the symptoms you are having but I'm assuming the engine is burning oil. Valve seals control the oil that lubricates the valve stems and prevents it from seeping into the guides in excessive amounts. The piston...
Pistons with spark issues
Hello there, a few different components can cause the engine to lose spark. It could be a fouled or faulty spark plug, distributor, or a wiring issue. I recommend having a qualified technician, such as one from YourMechanic, come to...
Can you put vortec heads on 86 350 with high top pistons
Hello. The Vortec heads should bolt up to the 86 350 block, however, they will require a different manifold and engine management system. In regards to the high top pistons, I would calculate the compression ratio that should theoretically be...
with the#1 piston up were should the rotor button be pointing
The rotor button should be pointing to the number 1 position on the distributor cap when the number 1 piston is at top dead center (on the compression stroke). The pistons come up two times during the combustion cycle. Once...
Might have blew the engine
If the vehicle is not starting, the most likely cause is the battery. If the engine itself has stopped working it will require diagnosis to confirm which component is malfunctioning. A qualified technician, such as one from YourMechanic, will be...
engine knock
If there is engine knock after running low on oil and it does not go away after putting oil in it, then the damage is done. The engine bearings are bad and more than likely ruined the crankshaft, rods, pistons....
Switching from conventional to full synthetic oil in high-mileage vehicles
I actually had a discussion with an engineer at Chao and this guy was an expert. I mean, they design all else. He said that synthetic oil can't do anything like that. But, I had to argue back at him,...
Rattling sound in 2004 F-150 Lariat when starting the engine on cold weather
Unfortunately for you, that is almost always a testing slap. It means that the bearings are worn and that the pistons around are slapping back and forth. If it makes that much noise, have a mechanic listen to and diagnose...
2004 Hyundai Santa Fey with rebuilt engine locked up
I definitely would bring the car back to the shop that rebuilt your engine to have them repair it. If the engine is locked up, it is locked up because something is broken internally, like a piston, rod, or a...
My car engine seems locked up.
The piston rods that connect to the crankshaft are most likely bent. The bent rods will cause the engine to not turn over. The engine may need to be replaced.
Pistons slapping on a '98 Forester
It's sounds like it is time for a new engine. Those have those boxer engines that are opposed and they just wear out over time, because they've got pretty much more strain than a normal engine and it puts a...
Oil burning
Hello. Oil can only get in to the cylinder one of two ways. Oil can get past the piston rings from worn or seized rings on the pistons. There is even a possibility of broken rings. The other way oil...
Engine makes metal-to-metal noise on a 2012 Ford Taurus SEL 3.5

Opinion about Toyota die-cast aluminum engines
There are well-built engines that last a long time if you change the oil regularly. Realize that those aluminum die-cast engines have matrixes built in them. Originally, they sleeve them down with stainless steel, which of course works quite fine...
Piston misfiring and oil on a sparkplug
Oil in the spark plug bore is caused by a leaking valve cover gasket. This can short out the spark plug and cause damage to the plug and coil, and also the spark plug boot. The valve cover gasket set...
Engine damage
It is certainly possible that the damage to the engine was done prior to you purchasing it. This does not necessarily mean that the people who sold it to you were aware that the issue was there. Sometimes things happen...
Brake piston seized after brake pad change
Was this the rear brakes? Many times the rear calipers have to be turned in with a special press that turns the piston and presses the piston in at the same time. This is because the parking brake is built...
