Rough estimate on (self) repair?

[Kiraush]

I've read through this, and also bumped it to see what the poster did.
But I have the exact same problems, and I'm almost certain it's not a BHG (yet at least :cry: )

But I was curious how much it would cost to replace the valves and anything else that would be causing white smoke at start up?

Am I missing something? If you are going to do all the work yourself go price the parts your going to replace and ta-da, you have how much it will cost you.

I don't have a firm grasp on car mechanics, I'm good with computers and it feels similar enough that I've been fine doing all my own repairs.
But I'm not sure what parts I need

Just the cost of the valve stem seals. $35-45.

If you're going to replace the valve stem seals, it's probably a good idea to plan on replacing a lot of the gaskets on the top of the engine. Valve cover gaskets will almost certainly need to be replaced, and the PCV hoses are probably going to be extra crunchy. If you've got a 7M-GE, you should plan on replacing the intake manifold gaskets for the Y pipe.

Once you have those parts off, you should also plan on at least inspecting, if not replacing the spark plugs. (You'll need to pull the spark plugs in order to get the valve stem seals anyway.)

If you don't already have tools, factor that in as a cost as well. For this job, a basic metric socket set, metric wrench set and screwdriver set should be adequate. Also commonly used for this job, a length of 3/8" nylon rope to keep the valves from falling while you have the keepers off. Also, a box of ziplock bags and a sharpie will come in handy for keeping stuff labelled as you take it off.

If you have to remove the head, things start increasing on a pretty steep slope for required tools, not just parts.

Tools I'm pretty set, I can borrow just about anything you can imagine tool-wise from my grandfather or my uncle.

Valve Stems 35-45$
Valve Cover Gaskets ?$ - ?$
PCV hoses ?$ - ?$


What would I need to remove the head for? if there are any reasons?


(Not being lazy, I just like having your guys opinions over the kids at Napa, you guys certainly know more.)

Removing head is just basic tools. You'll need torque wrench afterwards. I recommend doing valve stem seals with head off in my opinion. The other way seems to sketchy to me.lol

Alright Sounds good, thank you very much.

So as for a parts-list, is there anything else I should look into aside from these?

PCV Hoses
Valve Stems
Valve Cover Gaskets

Heh - I replied in the other thread as well.

If you do it with the head on you have a good list there.

If you take the head off - then machining the head may (probably) be necessary - for $$$! Plus headgasket... and I don't know what else - in addition to the above tools.

If you remove the head, I would absolutely get the head machined. In which case, you can just give the machine shop the new valve stem seals, since they'll be removing the valves.

You cannot (Or really SHOULD not) use a metal head gasket if you remove the head, unless you're going to tear down the block, and get that machined as well.

For removing the head, the 10mm allen key socket for the stock head bolts is somewhat unusual. I also wouldn't want to pull the head with the engine still in the car. It can be done, but I wouldn't, so a hoist and an engine stand would be good ideas.

Since you will already have the valve covers off you may want to replace the grommets and the screws that hold the valve covers down. These screws don't need to be super tight also. The torque spec on them is something like 22 in-lbs. Also, if you have oil around your spark plugs you will want to replace the #3 valve cover gasket (the black rubberized piece in-between the two valve covers).

For the #3 cylinder head cover this may be helpful:
