Poor Fuel Consumption 2001 V70 T5 Post Seal Change and Timing Blt

so any testing done with the fuel system throttle body --fuel delivery -pressure--etc---trans check ---any pending or active codes

Yes---- if you go to You Tube Video-- all that
is there to watch- if you play with the site some

If the engine oil is just low, and there are no apparent leaks around the cylinder head, timing belt area, camshaft seals, rear main seal, oil pan seal, etc., it's just a matter of adding the correct amount of oil or performing an oil and oil filter change. If seals or gaskets need to be replaced, this can become a big deal.

If you haven't had the timing belt replace (60,000 miles is the suggested service intervale) this is an overlap of having the timing belt replaced.
If the timing belt is not due for replacement and its the cam shaft seal that is leaking. Its a pretty easy fix. Remove the top timing belt cover , and the crankshaft sensor wiring you may have to remove the front engine mount . Set #1 piston at TDC, Loosen tensioner w/ spring slip off belt. **Remove sprocket pull out old seal with a sharp pick. Greese and install new seal make sure its flush with its bore . Reistall sprocket. Slide belt over Cam sprocket tighten tensioner. Install cover and mount (if applicable) Check timing marks by turning crank two revolutions.
** If CamSprocket Bolt is difficult to remove then remove valve cover and use a 21mm wrench to hold the Camshaft while you crack off Cam Sprocket Bolt.
You will see the groves on the Camshaft where you can place a wrench to hold the shaft.
After you replaced the seal replace the valve cover gasket ONLY IF YOU HAD TO REMOVE THE COVER TO HOLD THE CAM WHILE REMOVING ITS BOLT.

This is about as major as it gets.

Ok you have to disassemble the front of the engine, remove time belt, remove crankshaft sprocket, I warn you in these engines often is the oil leak by the seal of the oil pump, so I recommend you change the seal the pump and the camshaft and thus warrant you. Thanks good luck comments

Bad oil seals in your turbo ! The turbo has to b replaced thanx Chris

I have toyota corona 3s engine it smokes black and fuel consuption is high we have changed the engine oil and cylinderhead gassecate but still black smoke is comming what should i do

Your info is confusing. The rear cam seal is not inside the timing belt cover, and the crank seal is at the bottom of the engine, while the cam seal is at the top.

Is there oil at the top, around the cam seal? Or just at the bottom? It's common for the oil pump seal to leak. If you get the oil pump reseal kit, it contains the oil pump seal and gasket, as well as the crankshaft seal. Make sure you seal the oil pump bolts, Volvo has special copper washers for this purpose.

Just try to locate the oil leak before replacing any more parts. Sometimes it can be something simple like the oil cap seal or the oil trap housing.
