how much $ for top end rebuild?

hey. im sure theres tons of threads on this topic. but i have a 73 2.4 e mfi motor. im doing a top end rebuild. not sure if it really needs a rebuild. i never did a leak down or comp test. i had the car for around 2 years. the p.o. had it for 10 years. he never did anything to it, and theres no records that came with it. i dropped the motor to fix oil leaks, and said heck with it, i will do a top end rebuild. i have a local porsche mech who is really good. i plan on just removing the heads and cylinder and pistons, and take that to him. have him do all the work. and have me put it back together. what kind of money should this cost me? i know its kind of a general question. i dont think any studs are broken. not sure of the valves condition either. just curious to see what you guys spent on a top ed. thanks

Send the heads to Bob of Anchor Atlantic and have him do that work.

well, parts+machine work+labor. parts if you do it yourself gaskets, sealers, broken stuff try to keep the "while in in there" things to a minimum and special tools, try to borrow these. Machine work, this is the big one, if everything checks out (pistons, cylinders, heads, cams) than most cost is in head work. labor, best savings is doing it yourself-it's free. so best case $1500 worst case $ (new pump rebuild, several new heads, new pistons/cylinders, etc. OMG!! the great unknown. Lets not think that way, $1500 bucks is my guess

thanks for the replys. has anyone used anchor atlantic before? i visited there website and sent e mail to them. got a reply. basically its 750 bucks for them to do the heads, without valves, springs, or stud work. seems pretty reasonable. i havent had a chance to take the cams heads and cylinder and pistons off yet. im hoping everything is still reusable.

Search under "Anchor Atlantic" in this and the engine building forum. Many of us have used Bob's services and he's an excellent person to work with.

$750 for basic head rebuild???? That would be less than $400 down here. Get them back looking like brand new. What is it, the high taxes up there?

I just spent $1600 on my Carrera 3.2 heads, which included new valves/springs/seals and rebushing guides. No refacing required. My cams were pitted so I spent another $1200 to have those and rockers refaced. My Alusils weren't worn so I left them alone, as replacing can run serious $$.

Took my car in for a top end rebuild because of leaking valve guides in 2 cylinders. Estimate $4500 from a good mechanic with a stellar reputation.

Pull the motor....
Two broken studs, better replace them all. $$
The 2 cylinders with the leaky guides showing a more wear than the others. Dicey to reuse. Replace with Euro P/C's. $$$
Cam shows some pitting. $50 more to replace than resurface. $$
Clutch shaft update never done. $
135K on original clutch. Probably should replace. $$
Leaky oil sensor. $
All the original rubber lines are really hard and brittle. $$
gas lines are all original, 27 years old. Better replace. $$
Hell, while we're in there, why not do the wheel bearings flush the brake system. $
And so on, and so on.

So, I paid $20K for the car in 2002 and came close to buying it again in 2012. It should run for 100K or more without any major mechanical needs and the cost of the "top end rebuild" amortized out to about $160/month to drive for 10 years and 65K miles. At least, that's how I justified it to my wife. She either believed me or she's just being gracious.

The moral is, have some extra cash around for the unexpected.

You don't say how many miles are on it, but I've had my 73.5 since 1991. I think big question is to consider doing the lower end at the same time on any Mag case engine.

What is your oil pressure when hot - both at speed and idling?....By 120,000 miles, mine was low enough to cause concern and take action?

I did mine DIY and used Anchor. At 190K miles, they said the valves were worn so that's the only thing other than guides and all the other head work. Cost was $1200 as I remember. Everything looked and fit great near as I can tell. Cost for the entire top end was approx. $2000 I'd say which includes Anchor. I did some other stuff while you're in there to drive the cost up to 5K but no performance mods.

car has 64000 miles on odometer. not sure if thats correct. i would say its 164000. i took off the drivers side cam towers and heads cylinder and pistons today. i think everything looks ok. but really not sure what i should be looking for. looks like the valves have burnt oil on them. but good news, no broken head studs. and they are steel. theres none that are pulling out. should i replace the head studs anyway?

If you don't have enough experience detecting worn guides in situ find someone local to press on the valve springs when valve is slightly lifted.

Perhaps a local Pelican or Renn lister might be willing to come and give your situation a clearer picture.

They could bring a leak down gauge and might be able to assess mileage claim and valve guides.

Not trying to make it difficult on you. I'm just a "don't fix it if it's not broke" kind of guy.

The head rebuild on my 911 cost ~$1000 last year from Ollie's. It's not cheap when you get someone that knows what they're doing.
