View Full Version : Coolant in sparkplug hole! Also, removing A/C belts?

Since this might be somewhat urgent (in fact, I want to know whether it is urgent or not), I am reposting this, slightly edited, as a separate, new thread, since I have had no response to the post in the Died, won't restart thread (http://www.lancisti.net/forum/viewtopic.php?t=1292) (where, in hindsight, I now realize it did't quite belong anyway, since we now already know why she died and won't restart!).

Anyway, I finally got all the bits and tools I'd need to replace the timing belt and related tasks, but ran into one obstacle and made one alarming blunder.

First, the baffling obstacle:
I cannot seem to figure out how to get the A/C compressor belts off. Yes, beltS -- plural. One goes around the crank pulley, P/S pump and A/C compressor, and the other just goes around the crank pulley and A/C compressor alone. I slacked off the only two bolts I could find on the outboard side holding the comp. to a bracket on the engine -- the lower bolt hole on the bracket is arc-slotted and would apparently allow the comp to pivot towards the engine slightly to remove the belts, but the comp still won't move. Are there other bolts, perhaps on the inboard side somewhere, that I'd need to slacken, as well? I saw some "maybes" in the region of the oil filter (horizontal filter pointing to front of car), would prolly have to remove the filter to get at those properly, darn tight spot to even get a wrench into, let alone swing it at all... So I'm asking for advice first, before I do anything radical that could be ineffective and make reassembly more difficult.

Now, my boneheaded blunder, the source of possible urgency:
I'd taken the plugs out so I could turn the crank by wrench, and stuffed some paper napkins in the plug holes to prevent any debris from falling in. You may recall that I was dreading removing the plugs, as I knew from the pre-purchase shop inspection that at least one plug hole was nearly stripped and would likely need to be rethreaded with inserts.

BTW, Guy Croft himself (via email) warned me off the Wurth Time-serts for this application, as the counterbore tends to go too deep for proper plug seating and they can unthread too easily. He recommended Recoil Plug-Saver inserts instead, which are solid like Time-serts (and unlike Helicoils, tho' apparently Helicoil sells these sparkplug rethreading kits rebranded under their own label, but I digress...), but they have a knurled section of threads to resist unthreading. Amazingly enough, I found a kit with step-tap and a selection of inserts, house-rebranded at the local AutoZone (a US discount autoparts chain store) for US$30, so was no big hassle to get "the good GC-approved solution".

Anyway, back to my blunder, the stripped plug hole was #4, and with all the assorted plumbing and brackets and whatnot in the way, I simply could not get my hand in there well enough to start the tap properly (which may explain why the threads were semi-stripped). So I decided to pull off the heater hose emerging from the head right next to it. Of course, a fair amount of coolant splashed out before I could get the disconnected hose upright, and said coolant, of course, drained to where? You guessed it, right into plug hole #4, soaking right thru the paper napkin loosely stoppering the hole, and trickling right down into cylinder #4 itself. I will pause a moment now, so you can finish laughing and regain some composure.

Of course, my battery's dead from all those cranking attempts, so I couldn't just crank it'round a few times with the plugs still out to blow the spilt coolant (or most of it) outta cylinder #4. So I resorted to sticking long strips of cotton rag (actually cuts from an old cotton sock) into the plug hole, extracting it, wringing it out, lather, rinse, repeat, until a dry ragstrip re-emerged barely damp. There may be a couple-few CCs of coolant left in there, for all I can tell, but will it do much damage to leave things like this? Or so long as there isn't enough to block the piston's full range of movement (i.e., hydraulically lock before ful cylinder compression), would it all just evaporate and burn away when I finally fire up the engine again, no harm done?

Thx for any advice you could provide!

Hello Tye,
Sounds like you have done enough. I would crank the engine over a few times with all the plugs out and then fire it up with just the 3 plugs in. A short run should be enough to force out any residual coolant. You could push something like a broom handle down over the plug hole so as to get some compression in there but still allowing for any excess pressure to escape - not sure how brave you need to be to do that though!

Sorry can't help with the Aircon compressor fitting, however the PAS pump has bolts all over it that need slackened!

Thx for the reply; as it turns out, an acquaintance of mine (really a neighbor's father, with whom I've kept crossing paths) is part owner of a reputable service shop and has offered to exchange favors, so the work will now be done professionally. Good thing, too, as I think I got myself into trouble with the sparkplug thread insert (seems I may have failed to tap the old threads out all the way, as the insert wouldn't screw all the way down! :oops: )... I'll miss the satisfaction and bragging rights of being able to say I did these jobs myself, but this was an offer I couldn't refuse, and could lead to more business/income opportunities as well.

FWIW, I'd realized that I prolly only would have needed to shift the A/C comp. alone, not the P/S pump at all -- since one belt only goes around the crank pulley and the A/C comp., I'd definitely need to shift the comp. to remove that belt; the other belt goes around those two plus the P/S pump, but with the A/C comp. already shifted to remove the first belt, the P/S belt should be able to come free as well. At least, that was my thinking, but now it's outta my hands (and prolly for the best ;) ).

Well, now that I've got everything back together and fired up the engine again (took several jumpstarts to blow out all the cobwebs and keep it from stalling out, as it hasn't run since Thanksgiving, and the battery had died as a result of attempts to restart during early troubleshooting), I seem to have a fair amount of "mayonnaise" floating in my oil. 8O This, most obviously as a result of spilling coolant directly into a sparkplug hole, whereupon whatever I couldn't immediately sop up with rag strips had trickled down into the sump, sat there for a few months, :oops: and then got thoroughly emulsified by running the engine for a few miles down the freeway and back.

Will an ordinary oil change suffice to remedy this situation, or should I follow some more specific procedure? I've been considering a round of Auto-RX (http://auto-rx.com/) to clean out the innards anyway (one of the few additive/treatments well-regarded as apparently effective as-advertised according to the "oil porn pundits" at BobIsTheOilGuy.com forums (http://theoildrop.server101.com/cgi/ultimatebb.cgi)), so in that case most likely the new oil would be changed again within 1500 mi. or so, then yet again in another 2-3000 mi., so that oughta do the trick, non? :?

Tye:

From past experience with MoPar 2.2's (note - those things are pretty bulletproof, but the Lancia DOHCs seem even better!), an oil flush should do the job. There are flushes that you can buy at local stores, although you might be able to just clean it out with an oil change. The 'mayo' should burn its way out over time - shouldn't hurt. Anyone correct me if I'm wrong. 8)

BTW, does anyone know what I'm running? The build sheet on Fenice says she's got 6mm pistons. In MoPar parlance, that means I'm running larger pistons - is that the same with lancia blocks?

Buona fortuna,

I'd do TWO oil changes, as the stuff is cheap enough- but I'd change the filter FIRST. The reason is, water and/or coolant can degrade some paper filters in a way that oil doesn't, and result is a mess of pulp getting dragged into your bearings (sounds horrible, wouldn't want to risk it for the $5 filter).

Well, one can assume two things by "6mm pistons". It either means you have high-compression pistons with 6mm domes, or that you have 0.6mm larger pistons (i.e., the block has been over bored).

Since I've never heard of 6mm domed pistons, I'll assume it has been bored 0.6mm over.
