On the 1999 vw passat 1.8 turbo theres a hose thats wright behind the oil dip stick that goes into the engine block where can I find the replacement part for it?Or what is the name of this part if there is a replacement? thanks

COULD BE THERMOSTAT IF TOP RADIATOR HOSE IS NOT HOT AND BOTTOM RADIATOR HOSE GOING TO WATER PUMP IS HOT THE THERMOSTAT STICKING PARTIALLY CLOSE.IF TOP HOSE IS HOT THE RADIATOR,ENGINE BLOCK HEATER CORE NEED FLUSHING OUT.IF WATER PUMP WEEP HOLE LEAKING REPLACE WATER PUMP, FAULTY WATER PUMP WILL CAUSE ENGINE TO OVER HEAT.REPLACE RADIATOR CAP MAKE SURE YOU HAVE 50 / 50 MIX SOLUTION ANTIFREEZE AND WATER IN COOLANT SYSTEM. IF ALL LOOKS GOOD CHECK ENGINE OIL ON DIP STICK, IF OIL IN DIP STICK LOOK LIKE MILKSHAKE YOU HAVE BLOWED HEAD GASKET THAT WILL CAUSE ENGINE OVERHEATING WHILE DRIVING CAR IN SHORT DISTANCE AND ENGINE OVERHEATING.

Most likely place for oil into coolant is oil cooler, the aluminum box that mounts between the oil filter and a flange that comes off the block.

The dip stick tube is pressed into the engine block. Put a bolt into the top of the tube so that the body of the bolt goes into the tube and the bolt head rests on the tube (so it does not fall down the tube). Use a wrench (such as a Vise grip) to hold onto the tube at the bolt and gently work it back and forth, being sure not to deform the tube. Remove the tube and old dip stick. Replace the tube by forcing it back into the eng. block. Replace the dip stick - done :)! Some dip stick tubes have a gasket at the engine - others just **** up to a shoulder that is built into the tube. Let me know if this works. Thanks.

It goes in the place where the dip stick for your transmission dip stick is. Check the level per the instructions from VW. WARNING: DO NOT OVER FILL

Warm the car by driving around the block. Find the tranny dip stick, pull it, wipe it and check it again. If the oil level in in the cross hatch area, the level is fine.

Crankshaft sensor is located on the right side of the cylinder block behind or under the starter. It is fitted into the rear crankshaft oil seal hausing

is there a whistle from the turbo when accelerating if so the baering could be on the way out in the turbo.or blue smoke when accelerating could also be a sign.a blocked air filter would also cause it to **** oil through to the compression hose.

At tip of the dip stick there should be a patterned area about 1.5 inches long. The oil level should fall in this range.
You can probably download an owners manual from a VW owners forum or club.

I would check the oil pressure sensor and the oil pump itself. You can take the sensor out and use a mechanical gauge to check the oil pressure. If the oil pressure is within specs, you need a new sensor, if not, you need a new pump.

you have to replace the turbo

It sound as it your oil pressure senser or the oil pump needs replacing.
