    The car really needs a mechanical restoration since it's almost 30 years old(car only has 8k miles)

    Before pulling the motor out, I went ahead and pulled out all the F1 actuator bits. Pulled the under panel so that I can get to the shifter area.

    I then pulled the engine out. I used a modified 15mm wrench and a hammer to loosen the head bolts. The HILL Engineering tool can break when loosening these bolts, which is why I start with a hammer. I do use a another wrench or nut to keep the wrench from slipping... Then the head is off to get valve guides.

    Great work. Does it really need valve guides at 8K miles?

    Lol, no. But it makes the car much easier to sell if choose too.

    I mean you're past the point of no return now anyway, but I always though that the later cars like yours should be pretty robust in terms of valve guides. Not impervious to wear (thinking about the Auto Tech Nick videos), but should still be pretty good at only 8k miles. Be interesting to see what wear you find anyway. Data points always helpful. :)

    Wow, that might be the worst case of 'might as wells' I've ever seen!
