Whoa - I have a 2.7L. Now what?

My bad, for some reason I opened the first page rather than the last page and was referring to the pix of the combustion chamber at the bottom of the page. Sorry!

Got it – and you’re right, something got loose.

This is my first 914 I didn’t really have a sense of what was white, and I had no idea that this engine has been so highly modified, so when I was first driving it it felt OK and wasn’t lacking power and had a surprising amount of torque. Come to find out that the bolts on number three valve arms totally backed off so I think when that happen something may have entered the combustion chamber. Gulp.

Turns out the darn thing was only running on 3 cylinder and it still felt strong.

I haven't played with this type of engine before but from what I see or think I see is not good casting or machining to start with. Those holes in the top of the cylinder and the things in the valve pocket are things I don't think I have seen before.

Good morning Lee. Those small dimples are supposed to improve how the fuel atomizes, there’s debate as to whether or not they’re actually effective.

That other stuff you see there is when, I believe anyway, a washer got loose in the combustion chamber .

What does the piston look like ? If theirs nothing on the piston then the marks would be from a previous build. And in your other pic of the head, the other chamber looks to have nicks in the compression pad also.

Yeah, the washer damage, especially the curls in the edges of some of the holes, was what set me off.

The dimples still bother me as I seem to remember that being tried a long time ago but it disturbed/changed (if I remember correctly) the flow or something else through the combustion chamber. I didn't notice them until I did some editing of the pix to see more detail.

Hi gentlemen - hope you are having a good day. Will need to double check but I think the piston surfaces are all good.

[Tdskip]

Checked again and 3 of the 4 are in very good barely is ed shape.

This one has signs of impacting something - circled in yellow.

The top mark is not damage, just a smudge.

Called Brothers - going to bring everything up there next week and get a plan in place.

I don’t like having to write this sort of thing - but stay away from the “new” Blodget shop. Guy I was dealing with there turned into a total jerk despite my efforts to be a good/cooperative/ reasonable customer. In my experience things usually go down hill from there when a shop behaves like that up front...

Thanks for the referral to Brothers Richard.

Good to hear that ypu found a decent address for this rebuild. Please keep us updated with this great engine!

Thanks for the encouragement Mark, it was a really good initial experience talking to Brothers.

I am really glad I found this forum, the discussion on this thread and what I’ve learned from reading others has been extremely helpful.

How hard would it be to drill a set of 914 2 L heads for the additional studs that the case has on it?

I’m asking because it would make fitting the fuel system and exhaust a whole lot easier than whatever these funky things are that the previous owner worked up.

I assume I need to open up the valve size a bit to help it breathe better?

Thanks!

[Type 4 Unleashed]

Your talking a sizeable amount of money now. Regardless of the valve size's you go , the pricing will be about the same. I don't know what cooling system you have, but I can tell you this, the head tin is modified, the spark plug locations on your heads is neither the same as a 2.0 or a 1.8 ltr, so if you go 2.0 ltr heads, the cooling tin will have to be modified for the 2.0 plug location.

You will have to go a completely new exh system, and a good one is not cheap. Int system is another isssue. The bottom end, at least new rods, more than likely a new cam & lifters, cam choice will be up for debate, and I recommend Tool Steel lifters.

If it was me, I would just work thru the issues of the existing heads. 1st, I'd disassemble them, then clean them up, then see where I am at.

Good morning and thank you for the response Richard. Let me clean everything up and get some more pictures posted.

This car had a really funky totally custom exhaust to connect it to the turbo and it may well be that upon further inspection it’s usable with a more stock exhaust set up without any additional work.

As a relative newbie here it can be difficult for me at times to see past how it came to me versus what I’ve got/it could be.

Hope you are having a good weekend gentlemen.

[Tdskip]

Doin some cleaning before dropping it off.

This car had a oil lines flowing everywhere set up to feed the turbo and other stuff that I believe I can simplify significantly. In a normally aspirated engine I would simply have the oil pressure sender instead of this contraption, correct?
