Last night I spent over an hour removing my rear main seal. I don't mean pulling the trans and clutch, I mean just getting the seal out of the block. There has got be an easier way. The seal was dry and cracked and stuck fast to the engine. First, I had to break things free by placing a flat-head screwdriver against the seal every few millimeters and driving it hard with a rubber hammer until a "snap" is heard. Then I had to drill out a series of small holes around the seal through the interior metal "skeleton" of the seal and screw in a metal screw to pull like hell on. The pulling and tugging probably took about 40 minutes of grunting, sweating and cursing. Is it u…

I just bought a 71 240z recently as a donor for my 73, I have gotten what I need out of it but now I want to either sell it all or part it out. I have the complete engine that I don't need and I'd rather someone else who needs it, have it. What is a fair price to ask for it? I'm not looking to rip anyone off I just don't have any idea what its worth.

Hmmmm the alignment pin below the bolt does not align with the holes in the front cross member. The pins are ~3mm too low. The catalog says 62-600 [70-83] and the car is a '71 so I don't understand. Before I slot the existing holes any insight?

Okay, I've pulled the transmission and replaced the rear main seal, trans. input seal and trans. output seal - the whole interior of the bell housing was coated with a nasty mix of motor oil, gear oil and clutch dust. Now it's time to reassemble. Do you use loctite on the flywheel bolts? Red or Blue? Do you use anti-seize on the flywheel bolts? What about the pressure plate bolts? Is the flywheel or pressure plated coated with any kind of rust inhibitor? If so what is the best way of dealing with this? Should the pilot bearing be greased or oiled or dry? Sorry about all the questions, but I don't want to have to pull the transmission again anytime soon. Thank you,

In the FSM, it gives valve specs for "cold" and then for "hot." Question is, if valve clearance is set with the engine cold is it necessary to to re-set with the engine hot? I've talked to several mechanic friends who all disagree, some say set cold an forget others say set it only when hot and others set when cold and re-check when hot. This is not something I want to do several times.

Hi So I'm looking to buy a new water inlet fitting (pass side of front cover, above alt) for my F54 L28 and I've come across plenty of inlet fittings for L24/L26. The thing is the pics shown for these L24/L26 items look virtually identical to the one currently on my L28. Are they interchangeable or is there a difference? Thx!

Hey I just started my first z restoration. I am currently swapping parts over from a 73 to a 72. I am converting the 72 from automatic to manual. Everything has swapped over well so far, until I found the clutch hard line, running from the master cylinder to the clutch hose on the slave, on the 73 is in bad shape and wont swap over well. Does anybody know where I might find a clutch hard line? Any help would be greatly appeciated. Thanks.

I'm looking to get my camshaft reground locally and i've come up with two possible grinds that will suit my needs. I primarily drive this car on the street, and take it to the strip every weekend. I'm looking for something that would wake the car up from about 2000 to 6500 Rpm These are the two grinds i've been looking at, and i'd like some opinions / input on them. 1) Lift(In/Ex): .460/.460. And the Duration is (In/Ex): 274/274 2) Lift(In/Ex): .460/.460. And the Duration is (In/Ex): 274/280 And a 3rd option which i'm not so sure about is this one, Lift(In/Ex): .460/.460. And the Duration is (In/Ex): 270/280 MSA sells this grind and i guess the car really bogs down un…

Im hoping that there may be a simple way for me to solve my issue, and the forum seems to be the best place for answeres. After limping home as a moving cloud, i realized it was time for a new head gasket. Seeing as how i have done one in my jetta, i figured it wouldnt be that bad, and up until not it wasnt. According to my manuel, i needed to put a wood wedge in the chain in attempts to keep it up. This worked well until trying to install the head once again. Now after the head is bolted down, im attempting to install the cam gear with the chain in the correct location, and am finding that i have about 1/4" that i need to make up in order for the gear to slide over the c…

My rear end is 3.545 Current transmission is 1 - 3.321 2 - 2.077 3 - 1.308 4 - 1.000 5 - 0.864 The trans im looking at is this 1 - 3.062 2 - 1.858 3 - 1.308 4 - 1.000 5 - 0.745 I feel when im going through gears the powerband drops off when going to 3rd, i want to remove this. I also drop a lot of RPM while shifting. with this new transmission my 1st-2nd gear should have slightly slower acceleration but a higher speed in each gear with the benefit of being closer to each other it should be slightly "faster" correct? Will swapping to the new transmission alleviate this problem?

Just finished my first real road test and I have a couple of questions. I'm running a Hi Volume oil pump on Valvoline racing 20-50 for the zinc content. Is the normal oil pressure 80 psi because that's what I'm reading ? A question for you triple guys out there. I have an N42 with a E88 head, mild cam, headers, and 40 DHLA Dell's with 30 chokes on a Cannon manifold. It seems to pull hard to 4000 but above that in 4th I'm falling off. Do I need to go to 32 or 34 chokes ? What are you guys running ? Jet size seems to be ok, I had to bring it down from 140 to 130 because the plugs were reading rich.
