Some of you know that after my HG job I continued to loose coolant. First time I refilled the reservoir I just figured it was an underfill on the coolant. Second time I opened the radiator cap and noticed it full so again figured it was now full and things were fine.

RFJTOY, his son and I heaed out to Anza last weekend for a quiet trip. Couple of nights above the squeeze. Coolant when we arrived at camp Friday was find. Wheeled Rodriguez and Oriflame canyons on Saturday and checked it again at the end of the day. Reservoir was empty again so I looked under the oil cap - DAMN - same milky gunk I'd seen after the HG went the first time. Filled the reservoir again and we headed home Sunday instead of doing what we'd planned - Diablo Droppoff, out Fish Creek and then up Coyote Canyon for Sunday night and home early Monday. Really bummed about that.

Took the truck back to shop that did the work. They found a hose clamp loose at the top back of the engine and the coolant had been dripping down onto the manifold burning it off which is why I never saw any on the driveway. The kept the truck all week doing pressure tests etc. and never saw the same results they had before they replaced the HG.

Right now they are 'hoping' the gunk in the oil cap was just due to residual moisture in the system - they did obviously put new oil in when they were done with the HG. I did have A LOT of coolant in there after the HG blew. They ran the hell out of the truck all week and kept an eye on the oil cap and said it was getting less and less after each time they'd wiped it out.

I've put about 500 miles on the truck since the HG so I went ahead and changed the oil today to get rid of what they'd put in and hopefully rid the system of more moisture and any that may have gotten into their new oil. Cheap insurance and easy to do.

I'll still keep an eye on the coolant reservoir and the oil cap for the next couple of weeks to see. I did notice quite a bit of coolant splatter under the truck when I drained the oil so I know it was leaking out of the system and hopefully not into the oil.

Shop's fear was that they may have pinched the new gasket, but compression tests, etc. don't appear to show that. Owner was great thru this talking to me personally and acknowledging up front w/o me asking or saying anything that if it was the HG job that it was on him to make it right. That'd had been his rep from the folks that recommended him to begin with. Very honest and straight forward about it all.

Miata is going into hibernation for a few weeks and I'll drive the truck to see if it was just residual moisture or not and if the coolant reservoir stays full!
 
Best of luck Brent! Fingers crossed!

Hopefully everything turns out ok. Good luck.
 
hang in there
 
Update...not celebrating yet, but one week of driving the beast after Hanlon discovered the loose clamp on a coolant hose and I'm not down one drop of coolant!!!:bounce::clap::bounce2:

Except for a slight 'stumble' at idle occasionally, she's running like a dream.

I'll probably put about 1000 miles on this oil change and do a Blackstone analysis. This is the second oil fill since the HG, so I hope the oil Hanlon put in got rid of any residual coolant/moisture in the engine and this change will come out clean. Think it's worth it on this batch of oil or do one more in a few months and then have that batch tested when it's time to change it?

I know it's less expensive to drive the Miata as a daily commuter, but I do love driving the cruiser better!

:cheers:
 
I'd wait a couple of oil changes before doing an oil analysis. Otherwise, you may freak out unnecessarily. Just use cheap oil, let it be for 2000 miles and change.

You're probably right Eric!

I'd forgotten to check the underside of the oil cap for the milky moisture burn off gunk when I looked at the coolant reservoir on Saturday so I checked it yesterday. Clean as can be! That's even better news than the coolant still being full!
