So I'm debating doing the top end on my 1.7 I recently dropped a valve on.
Looks like I can buy all items from AA performance. Can I just buy the 1.7/1.8 96mm P&C and the 1.8 AMC heads and call it a day? I'm getting confused on what I read about opening to 105mm bore on the 1.7 heads for 96mm Pistons. The AA website talks about modifying heads to 103mm bore. I guess I could also just use 2.0 heads, but my tin wouldn't match. Sorry for being dumb... |

Just going to post this - take as one man’s opinion
I wouldn’t not open the bottom end and do bearings etc after a dropped valve. If it is truly all well and good it can be put back together with those good bearings (IMG:style_emoticons/default/poke.gif) The dropped valve is symptomatic of an abused engine. To put money in new heads and not redo the bottom end . . . I couldn’t bring myself to do that. Engine is out, had a hard life, probably other issues not far down the road. But that’s just me and in my opinion explains why we see so many stories on here of dropped valves, rod knocks, and T4 engines that just don’t seem to last. I won’t hold it against you if you don’t but felt compelled to to offer that perspective. |
