definately. your rods are probably bad or bent pistons may have scored the walls at an angle cuz the rods wernt straight due to the bearings,ect. time for a total rebuild or another engine.
Q:How does a jet engine remain lubricated it its main bearings?
Oil lubrication is done by dry sump - Dry sump for jet engines (separate oil tank) - Typical oil tank capacity of a JT9D engine is 25 liters - On jet engines - oil is prayed on main bearings then scavenged back to the oil tank - Oil in jet engines is cooled by a fuel heat exchanger (radiator) - Jet engines only use synthetic type oils - such as Mobil II or Esso/Exxon 2380 - Note to Piero - As you know, main bearings leak oil when engine failed and is windmilling - In case of absence of bleed air pressure -.
Q:Skating question about bearings and wheels?
you didn't get the bearings seated in the wheels correctly. Take the wheels off the trucks slide one wheel back on the axle press firmly and evenly to seat the bearing. You might need someone who can give it a bit more muscle flip the wheel over and repeat. do this for all 4 wheels. If there still is a problem, take them to a skate shop. They have a bearing press that can install the bearings.
Q:Help with my bones reds skateboard bearings?
Don't buy anything from anyone you don't know. Never buy from Trademe or eBay because somehting might be wrong with it. If you're going ot buy online then go to a trusted skatesite or a skateshop. Your Reds are probably dented causing more friction. Just pick up some FDK's ($10 abec 3's) or some new Reds.

Which bearings?. Are they the wheel bearings, the crank bearings, the headset bearings, or the pedal bearings?
Q:Cleaning out my skateboard bearings?
first of all NEVER use things like hyd. peroxide or sewing machine lube or WD-40. it clots up, collects more dirt and actually can cause more friction between the ball bearings and the shell. and absoloutly never use water, unless you want rusted shackles. only use actual skateboard lubricants, top kind out there right now is Speadcream by Bones.
Q:Can i replace the rod bearings by just dropping the oil pan?
I consider Rakel. If the connecting rod bearings are long gone.....then so is the crankshaft. it is going to could be became and the right length of recent rod bearings put in. it particularly is particularly not a activity with the engine nevertheless interior the vehicle.
