46 Merc PU Engine overhaul
Some of you boys will recall me having some issues with antifreeze in the oil of my 46 Merc (Flathead V8). Over the summer I flushed the rad, added IRONTITE and changed the oil with oil treatment every 3 weeks. It worked, as every time I used it it purred like a kitten and ran well.
Unfortunately I decided to take it for one last "dump run" without changing the oil and worse, without checking the rad - my first mistake. At the dump I noticed the oil pressure very high and then the temp rose....turned it off to let it cool and added some water. It barely started, but since we where on our way home I persevered.....that was my last mistake. Half way home (it's only 10 minutes each way) she shut down with a thud  Seized it - DAMN!Mrs. E-tek had to come and tow us home.....  Anyway, end of summer is here and it's time to tear it down to find and fix the isssue. I'll add updates along the way (and as usual - encourage others to show their projects in progress!!!)  First things first - removing the hood. In a one-man operation, ingenuity is king!    The tell-tale GOOOOO...

Re: 46 Merc PU Engine overhaul
E-Tec sorry to hear about your 46 taking a dump but I know she is in good hands and will be running like new or better before Spring

Re: 46 Merc PU Engine overhaul
Yesterday I got the engine and tranny loose (looks like it hadn't been out for a REAL long time!) and hung it to drain until today. Today I pulled it out and put it on the stand. Tomorrow I'll tear into it and see what damage I did on that last ride....stay tuned!
     As crappy as it looks, it ran like a top. Sh!tty that it developed that water leak...sh!ttier still that last ride was a ball-buster! Oh well, when I'm done it'll have a cherry engine in a patina shell - maybe I'll really jazz it up, hot rod it too - it'll be cool to pop the lid at a show and have a nice mill surprise people! |

At least you don't have to worry about "torque-to-yield" fasteners!

Re: 46 Merc PU Engine overhaul
Is that an L24 in the background with round top SU's?

Re: 46 Merc PU Engine overhaul
E-tek, that is going to look sweet when done. I think you have a great project ahead of you
 Opening that bonnet when done will be the best show off.

I just sold my 260Z to a friends dad. L28ET turbo swap. From what I have heard/seen from local Datsun guys, most who plan motor swaps and racing go for 260 and 280's, while the 240's are now almost exclusive restorations. The 260 and 280's have thicker metal, more spot welds, and are stiffer due to the start of crash regulations. Their values are starting to go up, and now that 240z's are mostly resto's, their value is getting higher still. I can't wait to see it! Also, the flathead looks great!

Re: 46 Merc PU Engine overhaul
Thanks guys!!
Interesting stuff their crash. When I built Mrs E-teks car, It was 15 years ago and I was working on 25 year old assumptions, that is, use the light 240Z body, but swap in the L28 engine. It was reasonably good on the straights, but we had a lot of work to do in the corners. There was a guy with a 510 that ran 13inch wide slicks all around - he would just drive by everyone in the corners! |
