resurfacing/honing lifter bores

[cjt671]

Have you done it before on this car or heard of it being done?

Had a feeling they'd be fucked up. Probably easier to get a head from a wrecking yard?

2.8 heads then swap the valves

You will be much better off buying a "new" used head. I literally just got one off eBay for $120 shipped. You'll probably pay more getting that fixed (if its possible), then you would getting a replacement.

[redline380]

Yeah, you wont be fixing those. Would cost way more than another head

Me too man. Thing is it's probably mostly damaged from trying to get the lifter out

I'm contemplating getting a set of heads... But my dad and I discussed honing the bore without pulling the head which I don't like because shavings/grit in the head and crankcase etc..

I know used heads are cheap and I can probably do the job for 1/4 of what a shop would charge.. I'm just starting to lose motivation, it's been sitting for a month already... I'm mainly pissed because I let a buddy help me when removing the cams because I was under the impression that he knew a lot more than me but he wasn't being a delicate as I would expect when working on a cylinder head.. Can't point fingers or play the blame game because I let it happen.

What to do...

[mauromj]

Wow, that happened removing it? Time to get a new friend....

These should slide right out with a magnet. In my case, I just tipped the head upside down and they all fell out.

PS. Your cam journal is hammered too. Time for new head(s).

[redline380]

Seriously, how did he try to get them out? Try to wedge a screwdriver in there and pry them out?

What I don't get is if you are capable of honing the bore, how could you not take the lifter out without fucking the head up?

Exactly. He was using a god damn flat head and hammer. The lifter was mangle and got wedge maybe .25 inch below the bore.. It took a blind hole puller to finally get it out. But the whole time I had though that that might work best. Since there was already a hole in the top of the fucking lifter.

Other head looks fine, I've read of people pulling the passenger head without pulling the engine, is it even worth it to try? Or should I invest in a cherry picker?

Ho-leee sheeet x10000

I would donkey punch his ass for stupidity.

Edit- No idea on how to pull the head, I am a 1.8t guy. I would imagine you can take off both heads though. I'm sure I'd waste a good part of a day trying to before realizing I should have asked and then pull the engine anyways

[Zba]

If you're in the b5 game for the long haul get a picker

[mauromj]

Definitely pull the engine. I pulled heads off a 2.8 last weekend, and it was a major PITA. I was able to get the passenger side off without to much damage to other components, but the driver side was terrible. The timing belt cover attaches to the block and coolant hard pipe and it is impossible to get to those bolts without at least the core support off.

why not drill a pilot hole and screw a self tapping screw into it an pull it out .

Because it would just spin! lol

[cjt671]

I should have told him to stop and asked him to leave.. It's was awkward situation b/c he's higher ranking than me and that plays a role in civilian life if you know what I mean..

I'm reading old posts about people being able to pull the passenger head without pulling the engine.. I had hoped my first engine pull would be for a new set of turbos to go stage 3..

You fellas use the cheapo harbor freight picker without issue?

2.8 heads would be nice man.. I'm considering it, need to do more research

[mauromj]

Where are you at in PNW? I have 2 2.7t heads that I dont need.

[fR3ZNO]

Heads can definitely be pulled without removing the engine. I did it a few weeks ago on a 2.8. It's a lengthy job (took a weekend) but nothing terrible.

This is a shame man! But think of all the experience you are getting :)

Saw this over on vortex in case you might be interested ... http://forums.vwvortex.com/showthrea...ads-50each-obo

I'll be curious to see how you end up turning this around.

[zillarob]

No way in hell I would deal with bs of taking heads off in the car.
I've seen it done, but Id def pull the motor out so you can get to everything and do a better job.

[nynoah]

Generally speaking the best way to do any kind of work on the 2.7T is to pull the engine. No B5 S4 owner should be without a cherry picker. Its a necessary tool for owning a 2.7t.

[cjt671]

Figured I'd update here but we threw the bitch back together and we'll see how long it last till I really need a new head even though it was yesterday

[flame suit on]

[redline380]

Wow, I wouldnt have done that. That lifter bore is fucked

[cjt671]

I know. It was hard to do. We took down the high spots and ensured the lifter moved in the same way the other bores do.. Cars running with no issues.. Haven't driven it yet though. I'll post back when it blows up again, I wanna see how long it will be before it eats that cam

[jaychen]

A good attitude to have for short term enjoyment. These cars are old and will break. Fix it when it breaks and dont blink an eye until that point.

Your willing to run that and risk blowing your entire engine rather than just pay $100 for a new head?

Wow.

Yeah, I may regret the mentality one day, but for now I'll be young and dumb with a running(till it's not) b5 s4
Also I bought this as a project car,
Where I fucked up is selling my A4, I should find a daily, maybe a Honda lol

Yes I'm doing a science experiment

Wow.

The whole engine wont "blow". Absolute worst that could happen is he floats a valve, it breaks, and knocks a hole the that piston, possibly fucking up the bore.

So, yeah, I guess you could consider that a total engine failure lol

That is exactly the scenario I had in mind. That's pretty much blowing. AKA, replacing your whole engine rather than just the head.

PS. I said blowing. hehe

The main issue here is the gouge in the bore that even if you cleaned up the high spots, it will act as a larger than stock leak in the oil pressure system. This could cause overall system pressure drop. I guess keep any eye on it and let us know.

Yeah I'm gonna consider getting an oil pressure gauge if it stays running long enough. Just to see what the exact effect it has is.

[redline380]

Lets not forget about possibility of metal shavings getting into the oiling system.

I don't know what you don't just replace the head.

I understand all the risks associated with running this head. Let's not forget that this is a 16 year old car, I understand that it's no where near the best option. Best case the cam lasts long enough until I go to training and then transfer to my next unit.. Which is why I need the car in a running state, military will not likely ship a non running car and I'm anticipating leaving soon. I don't want to just replace the head without sourcing a performance set of valve train components and all that jazz. I also think it'd be a waste to pull the motor without throwing a new clutch and turbos in it, I don't have the extra money to do all that right now and even if I chose to spend some money on all that (8-10k) I don't think I would have time to do all that before I leave here.

Worst case the engine "blows up" and I start from scratch using performance components and have a reason to completely rebuild everything that I see fit

[Zba]

You guys are silly. The only thing that will happen is the lifter will wear again possibly taking the cam lobe with it. Why do you think the lifter had a hole in it from the get go? It stopped spinning. LOL at losing oil pressure due to a lifter bore

[slow ride]

What funny is that you laugh about it not that I said it :) I didn't say all pressure, but it is a larger leak. which is all the oiling system is a controlled leak. Open up bearing clearance and pressure goes down with the same fixed displacement pump. He never stated the original reason for all this work unless I missed it.

That's my hope.. Which is why we took down all the high spots to ensure free movement of the lifter, rotated the engine a bunch and check movement to the other bores.. Driven 15 miles so far.. Haven't gone into boost much though..

I've read up a bunch about lifter failure and a lot of people point the finger at diminished amounts of zinc in the oil causing more start up wear.. not sure the whole truth but possible I guess

No oil pressure warning so far..
And we got the timing right the first try haha

Got home and she was chattering like a diesel popped the valve cover and was pleasantly surprised
