boostman Posted April 9, 2017 Share Posted April 9, 2017 Started the car this morning and the engine is vibrating and shaking, It sounds ok (but rougher), so don't think it's a miss fire. Could it be the crank pully? It was fine yesterday did 300 miles and didn't miss a beat. If there's anyone near Rugeley that could help diagnos this that would be amazing as this is my daily. Thanks a lot! Quote Link to comment Share on other sites More sharing options...

Dnk Posted April 9, 2017 Share Posted April 9, 2017 (edited) Do the tipex test on the pulley Inspect the cap and leads on the dizzy, take the cap off and check the rotor arm and inside the cap If it has a missfire you can possibly narrow it down to a cylinder by removing each plug lead from the dizzy cap one at a time and seeing if that affects the tick over.

OK so the middle steel part will become detached from the pully? Quote Link to comment Share on other sites More sharing options...
Dnk Posted April 9, 2017 Share Posted April 9, 2017 OK so the middle steel part will become detached from the pully? /QUOTE] Eventually the pulley where the belt sits will separate from the steel center part which will stay bolted to the crank Put a line across and run the engine, if the line separates your pulley is shot Quote Link to comment Share on other sites More sharing options...

boostman Posted April 9, 2017 Author Share Posted April 9, 2017 Is the car drivable to my local garage, it's around 3 miles away? Don't want to do any damage Quote Link to comment Share on other sites More sharing options...
evinX Posted April 9, 2017 Share Posted April 9, 2017 Better not to drive it. You will get loss of power steering and such unless you have a mate follow you at quiet time. Get a febest 1/2jz crank pulley for around 100 of ebay..had mine over a year and its fine. Quote Link to comment Share on other sites More sharing options...

boostman Posted April 9, 2017 Author Share Posted April 9, 2017 http://www.ebay.co.uk/itm/121828479195 Best to do the timing while thyre at it? Thanks, is that a dampened pully? It's much cheaper than a toyota one, is febest a reputable make? Quote Link to comment Share on other sites More sharing options...
and1c Posted April 9, 2017 Share Posted April 9, 2017 Thanks, is that a dampened pully? It's much cheaper than a toyota one, is febest a reputable make? /QUOTE] I wouldn't even consider that pulley. OEM is the way forward, even if you get a good used one off keron or somebody on here.. Alternatively there is more expensive after market ones from Titan etc Quote Link to comment Share on other sites More sharing options...
boostman Posted April 9, 2017 Author Share Posted April 9, 2017 OK so I'll get a new oem crank pully, so may aswell change timing belt and tensioner bearing, aux belt and the water pump. Anything I've missed? Or you'd change while it's apart? Quote Link to comment Share on other sites More sharing options...
hemmjonny Posted April 9, 2017 Share Posted April 9, 2017 I think the febest ones have had good reviews of members on here from what I remember. Quote Link to comment Share on other sites More sharing options...

boostman Posted April 11, 2017 Author Share Posted April 11, 2017 OK had a look, it seams the cam cover seal has gone.... Again, would oil on the plugs cause a misfire? I just can't see the crank pully making the engine run like it is. Iv only ever heard a 4cyl misfire and it sound nothing like that. Quote Link to comment Share on other sites More sharing options...
boostman Posted April 12, 2017 Author Share Posted April 12, 2017 Anyone had this before? Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted April 12, 2017 Share Posted April 12, 2017 On my old NA engine, I once had the throttle coolant pipe come loose and fill my spark plug wells with coolant. The moment the engine got hot the engine misfired like crazy. Potentially oil could create the same affect. Crank pulley coming loose should not cause a misfire. Typically it will cause all the auxillary systems like water pump/alternator etc to start acting dodgy. Start by replacing your cam cover seals, clean out your spark wells and clean your spark plugs at HT leads. Quote Link to comment Share on other sites More sharing options...
sultanadnan Posted April 12, 2017 Share Posted April 12, 2017 Anyone had this before? /QUOTE] Yes I had the exact same problem as you, had to change rocker cover gasket and put new spark plugs, also wash out all the coil packs. Quote Link to comment Share on other sites More sharing options...
boostman Posted April 14, 2017 Author Share Posted April 14, 2017 OK so got the plugs out and 1-5 are ok but number 6 has a hard rough coating. Check all for continuity and It and there in good condition. Cleaned them up and put them back in, now changing the cam cover gasket. Any idea what number 6 plug is indicating? Thanks Quote Link to comment Share on other sites More sharing options...
