Another S52 swap... but this time with a newb!

Kilo, you were right about the Die, and so was Madjurgen.

On a more constructive note, I still don't see how a m12x1.5 "die" would fit over a m14x1.5 bolt/sensor... Is it possible? Wouldn't you need substantial amount of force to even start the die?

A lot of dies can be adjusted to fit, then you just run it over a few times

A 12mm die will not fit over a 14mm thread. It will have to be turned down.

Exactly the answer I was looking for. So essentially it would be more of a hassle to rethread a sensor than the head? I'll just tap the head. Already bought the drill bit and tap. Any suggestions before doing so from any experience person's point of view?

Also, my biesan systems kit came in today, after finals on wednesday I'll be tapping the head and rebuilding the vanos unit. Thanks for the response.

Use cutting oil it is only aluminum and will drill/tap eazy.

Can it be done without cutting oil or using some other form of lubricant?

[formula driver]

Wow, this is quite disapointing...

Atleast I learned a few things before it went south. You guys cant seriously think its easier to tap a head (might not be that hard but its tedious) than it is to make a cut to a hose and use a few hose clamps...

Ah I guess you will be ok with out any oil for drilling is you don't get it to hot. But I would use some for tapping so the thread dont start to strip.

You should use oil. For sure tapping, and preferrably w/ drilling as well, but just a little bit.

[jahnaboi]

Done with my finals... now the progress begins again...

[sheefo2k]

good now take more pics and keep us updated on the tap.

[jahnaboi]

Didn't tap the head. I ranked out. Lol. But I did do something better / safer and just as effective. I'll snap pictures for you guys. I already slapped it on but I'll probably fab up another one.

[jahnaboi]

Picture of the adapter I made with a modified coolant feed that was chopped then hollowed with a 11/32nd drill bit to fit the probe and a 1/2 inch drill bit to tap the inside with a 14mmx1.5 tap where the sensor bolts up to. Worked out fine, just very tedious work. Little to no extra metal to waste so its a hit or miss. I did it right the first time so I got lucky.

Looks good. Only worry is it'll read a lil off since the probe won't be in the coolant flow like it normally is inside of the head. But is easier so its a trade off. Looks like it worked out good.

[jahnaboi]

I tried drilling in as far as I could, but you could only go so far till the metal gets thin for the face that mates on the head. If I went anymore the threaded nipple would have literally came off the housing of the coolant feed. But what I did was I actually cut 1/4 of a inch of the thread off from the threaded part of the feed so that the probe was exposed about 1/2 inch within the head. This should allow it to read correctly and be grounded to the head.
