ah i meant no signs of coolant, so i'm just gonna wait until the HG job for new oil just bc i wasn't planning on it so money is a little tighter than usual, otherwise i would. but since the HG job includes new coolant and new oil, might as well just let them do the swap.Cool sounds like a good plan. Theres some coolant in your oil though. I did oil analysis even after replacement and there was coolant in there a while. What hardness steal does MAP use? I didnt trust it. Better be tungsten carbide for $150. At least ARP washers specify 8740 Chrome Moly heat treated.
idk ab what kind of steel they use but on their website they say "8740 chromoly steel 12pt nuts" so not really sure if that also includes the spacers but i doubt they have a justified reason for charging $15 a spacer.
i keep getting confused on what the machine shop does and what it's worth. the shop i'm having do my clutch (URW for reference) says per manual it's a 17.1 hour HG job, and then plus fluids gaskets and machining charge, worst case price i'm looking at $2750.
the other shop which is more or less just a general repair shop (SJM for reference) (i trust this shop, been going there for 5+ years) tells me 14hrs for labor and then maybe $1000 for their machine shop to do their thing, totaling maybe $3000, maybe more.
the part i'm so confused by is URW tells me the machining would be $500 total, worst case. he tells me they put the head on a vacuum plate to check for cracks as well as valve seating, then it's like $250 to deck it ~.001.
SJM however tells me they put the head in some crazy machine to check every part to see if it's to spec, and they do some magnetic particle/xray/uv light/sciencey bs, and that is also the reason they would charge ~$1000 for the head machining job.
now, SJM is a shop that your grandma would take her car to for overheating. URW is a shop that your grandpa would take his MKV Supra to for a manual swap.
it's just so hard to choose which shop to go to when one tells you they will cover all bases and the other says i'm getting ripped off for $1000 machining job.
any input?
