| you have 2 cam seals 2 rocker cover gasket seals 2 D rubbers for the rocker covers You have 1 front crank seal 1 Rear main seal Basically the only easy one to do is the rocker cover gaskets and D rubbers The cam and crank seals require removal of timing belt etc Rear main requires removal of transmission or engine. |

| I havnt taken the 1JZ apart yet, the D rubber is the half a circle (D shape). Not sure if the 1JZ has them, but alot of manufactures when they bore the bearing races they use a D rubber to seal the outer edge of the head. But if the 1Js dont have them thats a plus, cause they always become brittle and poor out oil lol |

| 2 cam seals 2 rocker cover gasket seals 2 D rubbers for the rocker covers You have 1 front crank seal 1 Rear main seal ^^^^^^ so if i replace all those seals there is no possible way that oil can leak from my actual engine ? and are all of those seals available from toyota spare parts ?? |

| It also may be leaking from the head gasket near the pressure feed to the head which is located on the intake side of the motor right at the back. |

| You dont need to purcahse D rubbers as they are factory alloy, not rubber. You seal them with silicone. Waste of 20 or so each lol. There are PLENTY of other places it can leak from other than cam seals and rocker covers. Like stated Turbo return lines, High pressure feed to turbos (block and turbo) Head gasket Front crank seal Rear main seal (common culprit) Like cameron stated pressure feed to head cam sensor seals Oil pump gasket if bolted to block sump gasket (1JZ has a 2 piece sump so there are 2 areas to seal) And there are things I have probably forgotten about but thats enough for tonight to much to drink If your rings are worn out, and you are running high boost you will get large ammounts of blow bye which can create positive pressure within the crankcase and blow seals out. MANY MANY areas, its not just a matter of replacing a few seals. If you dont want ANY leaks, pull the motor out and replace all gaskets and seals. |

| nathan its probably alot easier if you just washed your engine down really well with degreaser (be mindful of your electronics and other area's water shouldn't be) run the car for a while, maybe even a day or two. and then look for where the oil is coming from and fix that. if its leaking on the ground have a look where the puddle is and then roughly trace it back up. would be alot easier then buying all these unnecessary seals and hoping its going to fix it. |

| ^^^ definately the best way, TD5 disco, major oil leak, cleaned motor, ended up the landrover dealership mechanics (where it had been previously serviced before getting peeved at there service and transferring to us) stripped out the rotary oil filter housing cover threads, and thought they would just leave it without repairing the threads haha. Few helicoils and new bolts and walla, no more major oil leak, something so simple can cause a major oil leak. |

| Don't forget to check the turbo oil lines, I had one of them leaking on me. It was pretty annoying when I finally realised what it was.. |

| My bet is the front crank seal. I have just done mine, no more oil leak. The muppet who put the previous seal in made a hash of it. |
