I ' d certainly include a section in the resume that describes your rapid turnaround , and request a sit down demonstration of skill , eye , detail , process , etc as part of the interview ? <| sep |> Uni student hereHave been lurking and I think some sort of testosterone supplement could help with the issues I ' ve been having slow muscle gain , high voice , weak mental state , etc . I want to try and get it from a doctor to make sure I stay safe . Any tips ? Should I ask for TRT , or something lighter like Clomid ? Any recommended readings ? <| sep |> I believe everyone has a different experience , here is mine . 1984 DatsunNissan 720 4 X 4 . NAPSZ engine 2 . 4 ltr . They are KNOWN for blowing head gaskets usually due to bad manufacturing of head AND engine block during the 80 ' s . not just my opinion , google it . I bought this truck 7 years ago and me and the used car dealer both agreed , it had blown head gasket due to all the White smoke it was blowing burning coolant . NOTE WATER will not compresscatch fire . Anyhow I bought and installed a little 6 oz tube of radiator stop leak . Stop leak looks like copper colored salt . As a mechanic I KNOW stop leak can seriously screw an engine . Stop leak gets hot , finds the hole that ' s leaking coolant , and Melts into that hole . It ALSO CLOGS UP other holes that should NOT be stopped upclogged . So I took a chance . I got her home , and drove her for the next 5 years , ALWAYS watching my coolant temperature . I got lucky , it worked for those 5 years . Then 1 day I was driving 15 mph in my neighborhood , and all of a sudden , she got loud . Thumping , chugging , struggling , and louder every minute . I seriously thought I had a bad bearing on my crankshaft down below , because the soundchugging , sounded like it was coming from bottom of engine . Wasn ' t the bearings , it was blown head gasket . So I pull her out to do full on rebuild cause I knew something was wrong . Compression test showed me I blew head gasket between # 3 and # 4 cylinder . Here is an album of beforeafter pics . 1 st pic is the day I got her home , 7 years ago . SO , what happened was , 7 years ago , a water jacket INSIDE the head , above cylinder # 4 had rotted thru and developed a crack . Crack is BETWEEN the 2 valves . Crack was probably due to previous owner not changing coolant ? IDK . SO , the crack poured coolant into the cylinder , thus the white smoke . Stop leak sealed the crack , I drove another 5 years . Stop leak finally FAILED , the crack opened up , dumping coolant again into cylinder . Beings that water doesn ' t compress , the pressure let loose between 3 and 4 . That began the chuggingstruggling . Because every time the 3 cylinder was firing , it was pushing gas and pressure into 4 , while it was on different stroke , and vice versa . Every time 3 or 4 would fire , it was blowing into the other cylinder . The engine was literally fighting against itself . That ' s my story and I ' m sticking to it . Got a good head off ebay for $ 230 . Bought a spare engine for parts , spare engines head had SAME CRACK between the valves . Thanks Nissan .
