Topic: Block/Head oil leak *all new shit* WTF? (Read 7720 times)

Blew a sleeve on the B18A ls/vtec. Had a B18B block machined, decked, using a new LS headgasket (same as I was using before). Thought I could finally start it back up today, and pouring the oil in, I see it coming out of this corner.

I can't figure out what it could be, and I'm just about at the end of giving a shit about cars. WTF?

The common cause have been discussed before, and there is a thread in hybrid tech about a similar issue...

Do you have a link, any thoughts about it, or should I just know that you saw it on the internet?

More like dealt with it in the real world several times. Nice try though Steve.

If either the block or deck have been milled at some point, there is the possibility that the dowel pins are bottomed out in their respective counterbores in the head and block. You can trim them down if this is the case.

Also, the use of a VTAK head gasket is recommended because the passages line up to the VTAK head much better than a non-VTAK gasket does. Also, the copper rivets that hold the multiple layers together get squeezed betweeen the head and block with a non-VTAK gasket. IMO, that is less of a concern than the alignment of the coolant passages.

I have found that most LS-V combos will weep a bit of oil unless you smear a light coat of RTV I prefer ultra grey) around the oil return passages on the head gasket.

The other thread is 4 threads below this one. Not too hard to find, but I guess you didn't even bother to look.

You must understand. I throw everything down in the garage, and make a post. I'm a GD/Pron/FS kind of guy, so I rarely read tech stuff, and when pissed off, don't have the patience to search.

I think it's probably the dowels being too tall, and I also think 40 cal for dinner sounds nice.

Lol.

It's gotta come back apart no matter what the problem is.

Has anyone with a milled D16 ever had this happen?

i suspect dowels being too long sir.

ratcityrex · « **Reply #8 on:** August 30, 2010, 03:38:31 PM »

Pull it apart, shorten the dowel pins, make sure you have a vtec head gasket and not a ls head gasket, and then copper spray the head gasket or put a light mount of rtv around the oil passage return. Ive never done the rtv thing but Ive HEARD of many people doing in. I have never done it and never had a problem, but I always copper spray my hg's.

if you got your block/head milled and trimmed the dowels accordingly and it leaks i suggest go to a different machine shop as there not cleaning it up enough or not milling it flat.

No problems with my d16 w/ 0.020 decked off the block and untouched dowels so far. ;D

I think its your garage. Strange things going on in that garage

jabberwock · « **Reply #12 on:** August 30, 2010, 09:30:53 PM »

Mine is milled enough for a half tooth, dowels untouched, and I have oil fucking everywhere.

HiProfile · « **Reply #13 on:** August 30, 2010, 10:44:15 PM »

I can't stand this about your sig pic. Fucking retarded women not trimming tags off their undies. WTF is with that?

That aside, jabbercock, you either failed at ls-vtak or a trolling on that one.

Dowel interference seems to be more common than not. It seems Honda didn't make the holes deep enough, or assumed B's would never need to be milled.

jabberwock · « **Reply #14 on:** August 30, 2010, 11:02:07 PM »

I'm inquiring about D16's. With the dowels in the head they stuck out maybe 1/8 to 1/4" and looked like they would fit fine in the block.

Not trolling now, this is a genuine question. I didn't check the head before I put it on this block but I had it checked when I built it last time... but that HG popped (I forgot the dowels that time). Always had ARP's.. never really overheated just kind of ran hotter than I would have liked and consumed a small amount of coolant. So I replaced the HG, broke a head stud in the process, got a new block which was milled and assembled the bitch. Now I have oil all over the fucking place. I'm hoping it's just the usual VC gasket and maybe my cam seal, but it's pooling on the block under the head on the ledges.

Well Fuck a jigaboo, I'm gona have to go take a look at my extra ls hg I have in my garage when I get off work now. My extra one is a felpro.

Fel-Pro - Head Gasket
Part Number: 9698PT

Just sayin...

bigdaddyvtec · « **Reply #18 on:** August 31, 2010, 06:30:23 PM »

If using OEM (OR GE since they just hog out OEM gaskets) There is an "up" on the gasket on one side that is outlined by the black layer being cut out to have the U and the P apear silver by exposing the silver layer.... Seen a couple in "backwards"... LOL

You kind of have to be an oaf to put a DOHC VTAK head gasket on upside down.

The oil galley passage makes it kind of obvious.

My LS ebay gasket is exactly like that.

Stealthmode · « **Reply #22 on:** September 01, 2010, 07:34:53 PM »

After further drunken review, I completely fumbled where the rivets are, were, and...yeah.

Got it all back together now. Just gonna double check everything in the next hour (drinking

) and then maybe triple check everything a couple drinks in, and then start it.

Maybe try putting an engine together sober?

I don't know... the reason I was losing coolant was because that little water line that goes to the thing on the bottom of the IM.. one of the clamps wasn't on. I just found it yesterday.. High Life will do that to ya.

HiProfile · « **Reply #26 on:** September 05, 2010, 12:09:02 AM »

At least you didn't leave the coolant out...

But I wanted to increase P2W clearance anyways before that happened.

It's a good thing it happened though: there was some gunk that made it to the mains & cut the bearings up. So sometimes things happen for a reason. Now I use a harbor-freight water pump to push simple green through my engines via the oil filter hole.
