    sorry what i meant is how its all in different categories
  2. DTT_Eruc
    i was trying another forum to see if i get another replies geeez lol
  3. DTT_Eruc
    havent got a timing light to know... i had it at the neutral position/stock...sooooo .....again i started the engine before i did the head removal and it showed vac and also the timing was at stock position and idle fine just dump alot of gas....reason for head removal had a slight bent valve on 11 and 12 exhaust(idk how it happened) but the engine was bought from someone etc etc etc
  4. DTT_Eruc
    yeah all the dots are lined up perfectly ...just did the screw driver test for additional clarification ...... still my question havent been answered yet " will the current clearance value cause this problem also" or is it just intake related(intake cam,boost/vac leak etc)
  5. DTT_Eruc
    oh i did check timing but i dont like using the crank pulley as it tends not to be 100% correct(believe mines getting worn out).... all marks seems to line up perfect and did the screw driver trick to make sure it was tdc and all marks line perfect ...... geeeeeeeez idk why little things does cause big problems lolzzz

    p.s this is my personal build and not a customer(dont do mechanical services) so everything am doing is trail and error on this project

    try a home made smoke machine had a very slight leak to the throttle body/tps......saw no other leaks from the intake(injector seals,gasket,vac lines) just the timing to check .... this engine produce vac before i took off the head but after i lap the exhaust valves(grit to fine) and due to human error on my side forgot to check clearance( first time dealing with head work on rb) lol...... but will the exhaust valve cause this issue being the clearance out of gap...
  8. DTT_Eruc
    well i havent drove the car/ran it for long to say for it to cause any major damages but it ran for a while with no heavy load......but what do you suspect it maybe?
  9. DTT_Eruc
    checked all lines last time i try to make the car stay steady at idle was at 2000 to 2500 rpm or so.....am starting to think its more to deal with the exhaust clearance that causing it not to idle at lower rpm since the clearance is tight..but i just wanna confirm with yall....dont have leak down tools but only a compression tester
  10. DTT_Eruc
    Bump
  11. DTT_Eruc
    elsewhere like? engine wont idle at 1000 rpm and if it try to will die and it shows zero value
  12. DTT_Eruc
    Actually no vaccum at all just show 0 on all gauges(ecu and boost gauge)....running tomei pon cam 262ex and 260in..... before i did the head work this never happened so i was wondering if is something to do with the clearances or timing .... but since the exhaust side has change was wondering if that would of been the cause
  13. DTT_Eruc
    Is it possible that tight valve clearance on the exhaust side can cause little to no vacuum on idle...... This is regards to a RB25DET NEO i got...Re done the head installing tomei 1.2 head gasket and lapp over the valves however after that was done the intake side was at nissan specs of 0.012 and the exhaust is way tighter(0.014 to 0.015) on all 12 of the exhaust... will this cause such issue... secondly my last chance was to check to see if my timing was off Running tomei poncams 260 9.15 Intake and 262 9.15 Exhaust

    So am going through my settings of my management and trying to figure whats best suited for the fan to be activated for my engine. I got a 16" fan on a 2 core rad.... After monitoring my temp sensor reading it sits around 85c on idle. Should i activate the fan to come on at 85 or activate at 90-95 then shuts off at 80 or 85 ?
  16. DTT_Eruc
    I know the post is out dated a bit but for those who contributed on there ideas/solutions just wanted to update yall once again.. Decided to find the strength and patients to pull off the head and BOOM! Valve #11 was surely the issue but strangely enough the valve is bent very slight so slight its hard to pick up in one glimpse. Also saw no contact on the piston and valve #12 seems to be ok thus far... Still leaves me to thinking HOW did that happen.
  17. DTT_Eruc
    Sooooooo... Just an update, i happened today got time to put back everything together and decided to do a compression test.... from Cyl 1 to 5 read 120 to 125 psi and for Cyl 6 reads 50... Jackpot of my problem lol but ik i still gotta take of the head....
  18. DTT_Eruc
    i forgot to ask ... if am using a tomei gasket which they only sell for 87mm bore and up,am i safe using it with stock bore of 86mm? and also do i have to skim the head to use there 1.2mm thick gasket. i was just gonna clean the head and block as perfect as possible...
  19. DTT_Eruc
    is it safe to purchase second hand arp head bolts just saw a buddy of mine having them for sale
  20. DTT_Eruc
    lol highly appreciate the patients and advice... head gasket no problem was just a bit optional on going on the arp but ill have no choice but to do so...... all this was really planned on the next motor build i had in mind .......
  21. DTT_Eruc
    ahhhh yes my dear friend it IS a disaster waiting to happen... is it my daily driven car? No it isnt.. am i planning on hammering it everytime? maybe,maybe not..... even if it makes 600 or even close to it does mean am putting my head on a block hoping it last forever.... what ill like is for the engine to at least give me a span time of 2 years so that i can gather all the essentials of having a properly built rb... so maybe 600 is a target but in reality ill go whats best for the engine at this moment .... so as you said it has been done for those with the luxury of spares or rebuilt.. for me once its up and running from there is buy abcdefg etc etc lol but i got u bud
  22. DTT_Eruc
    well if i do the HG since am there having no choice ill like to use the stock head studs till even if is not big amount of boost just want the car moving for now.... cause installing the arps wouldnt be hard doing after wards
  23. DTT_Eruc
    tomei 87 1.2mm on the stock bore(86).... well only until i see whats up with the head ill know what to do from there on..... dam why cant i just drive as is lol been working on this project 2 1/2 years now.....
  24. DTT_Eruc
    how much psi can the stock head studs hold for?
  25. DTT_Eruc
    the objective tbh was to do the 600hp on stock internals and hope it last till i can afford another head and block build.... so i really didnt want to touch anything inside but now i have to clear that "valve" issue ill have no choice but to do a fresh gasket and headstud(optional for me as funds are low) lolzz
