510T Posted September 23, 2016 Author Report Share Posted September 23, 2016 Looking like it. The parts were all fresh, I suspect the assembly was not handled professionally as I was told it was. 1 Quote Link to comment
shacks510 Posted September 23, 2016 Report Share Posted September 23, 2016 Did you pull the pan off and check everything out before putting it in? 1 Quote Link to comment
Draker Posted September 23, 2016 Report Share Posted September 23, 2016 wtf.. Do you still have the contact of the person that sold it to you? 1 Quote Link to comment
510T Posted September 23, 2016 Author Report Share Posted September 23, 2016 I had the lower pan off but did not take the upper off or check the bottom end really besides verifying that it had Eagle rods. I still have his info and he knows I am having issues. The crossmember is coming off and I am going to drop the pan in the next couple hours. Quote Link to comment

Duke Posted September 23, 2016 Report Share Posted September 23, 2016 :( I know the feeling. The first KA I put in my car years ago was fucked. Hope it ends up being something simple. 1 Quote Link to comment

DISLEXICDIME Posted September 27, 2016 Report Share Posted September 27, 2016 Pull the valve cover off see if it still has the top timing guide I had to replace my s13 tensioner with a s15 tensioner and remove that guide because the tensioner was failing and causing chain slap . It's a common problem 1 Quote Link to comment
510T Posted September 27, 2016 Author Report Share Posted September 27, 2016 It does have the top guide and the tensioner seemed fine. How would I tell if it went or was going bad? I do have a spare from my old engine I could throw on. I am partway through pulling the upper pan to check the rod and main bolts and bearings. I have to back the tranny off to get the upper pan to drop. I did find a few loose bolts on the upper pan so I feel like I should keep going with that. 1 Quote Link to comment
Draker Posted September 27, 2016 Report Share Posted September 27, 2016 What did the oil pressure look like? It a noise like that I would think there would be deviation in PSI if it were a bearing. The needle would probably bounce a bit. 1 Quote Link to comment
510T Posted September 27, 2016 Author Report Share Posted September 27, 2016 oil pressure was good, 40+ psi if I remember right. Quote Link to comment
DISLEXICDIME Posted September 27, 2016 Report Share Posted September 27, 2016 If you remove the guide you have to get the s15 tensioner 1 Quote Link to comment

DISLEXICDIME Posted September 28, 2016 Report Share Posted September 28, 2016 Did they machine the rod and Maine bearings? Quote Link to comment
510T Posted September 28, 2016 Author Report Share Posted September 28, 2016 Supposedly the crank was "polished" and the seller has no documentation or knowledge on the bearing clearances. Quote Link to comment
Draker Posted September 28, 2016 Report Share Posted September 28, 2016 Did you check with a digital or mechanical pressure gauge? Digital gauges can smooth the oscillations. Not suggesting it's a bearing.. just noting what I've seen with gauges personally. 2 Quote Link to comment
Noflers Posted September 30, 2016 Report Share Posted September 30, 2016 Took me about 24 hours, but I got through the whole thread. You're car is great and it was cool watching your videos, you're definitely getting better! Sorry to hear the terrible news, about BOTH SR's.Thanks for the thread, keep it up! 2 Quote Link to comment

Thanks for the kind words Noflers! I will never stop, but it can be quite the challenge to stay motivated during the rough times. I do have an update! Rag10 came by and helped me figure out what was going on. Our conclusion is that the crank was machined .010" but standard size rod bearings were used. The plan is to drop the crank girdle and plastigauge check the mains then order bearings, hopefully just for the rods. Crossing my fingers that that will do it and I can get back to burning up tires in a few weeks. 2 Quote Link to comment
DISLEXICDIME Posted October 2, 2016 Report Share Posted October 2, 2016 You would think they would have checked that wtf 3 Quote Link to comment
Draker Posted October 2, 2016 Report Share Posted October 2, 2016 I hope you're right! 1 Quote Link to comment
510T Posted October 6, 2016 Author Report Share Posted October 6, 2016 Checked the mains. They turned out to be ACL brand and the correct size, plastigauge showed clearance on the tight side of spec. Now just waiting for rod bearings to get drop shipped from Clevite. I hope it will all work out! 7 Quote Link to comment

510T Posted October 19, 2016 Author Report Share Posted October 19, 2016 Back at it! I was away on a vacation but never have been more excited to come home and get back to the Datto. My rod bearings were waiting! Always like to see parts made in Japan: As I R&R'd all the old bearings I came across another example of incompetent assembly. Pretty sure 8 halves make 4 pairs. #4 was missing half the bearing: During all this I decided to remove the ARP main studs and reinstall the stock bolts from my old engine. I have no faith that the engine builder or PO had the mains line bored/honed with the ARP studs installed and read a lot about them causing crank binding issues without. I torqued to spec and the assembly seems to turn a bit smoother than it did before. At this point I am finishing up cleaning the sealing surfaces of the pans and hope to have it back together by the end of the week. ;) 4 Quote Link to comment
