slugish before op-temp

Killa B · 12-20-2011, 03:28 AM

i have recently rebuild my 7mge, i have noticed it takes it about 15-20 minutes to reach op-temp. The engine runs really slugish when i drive it under op temp almost like ive lost 40% power its fine if its at op temp though. Also if it hasnt reached op temp and i turn the heat on it cools the engine down pretty quick i figured that was normal because its an older car. Im using Valvoline max life 10-W30 oil in it. does anyone know what could cause this. Is it just the engine hasnt broke in well enough yet?
